Get caching and more with this powerful cache plugin. Cache, optimize images, clean your database and minify for maximum performance.
MORE THAN A CACHING PLUGIN
WP-Optimize is trusted by more than 1 million WordPress website owners to boost performance and reduce page load times to improve your site's user experiences and SERP rankings in Google.
It does this in four clever ways:
1. It caches your site
Caching is the process of storing a temporary HTML version of your site on the server so it can be retrieved more quickly for the user.
It's a sure-fire way to ensure web pages load at lightning-fast speed. Turn it on in just one click.
2. It compresses images
Large images can really impact page speed load times. WP-Optimize makes it easy to identify and compress images to your preferred lossy / lossless settings in a couple of clicks.
3. It cleans the database
Your WordPress database stores everything that you need, plus some things that you don't. WP-Optimize cleans and optimizes the database to speed up your site and save server resources.
4. It minifies
On top of its three main features, WP-Optimize Cache also has the more advanced minification feature.
Together with caching, minification dramatically improves performance and page speed load time.
optimizeThere are 3 different ways to install WP-Optimize Cache, as with any other wordpress.org plugin.
We've built WP-Optimize Cache around the most advanced and powerful caching technology. Our caching tests and feedback from real-world users show that the caching feature alone can make your site faster than any other cache plugin or optimization. See these speed test results.
Yes; optimizing does not involve any "tricks" or poking around in dangerous ways. It involves running routine clean-up operations using well-defined, common MySQL commands. Nevertheless, we always recommend backups, which cover every possibility; not just database malfunctions, but hackers, human errors, etc. We recommend UpdraftPlus.
This is a "how long is string?" sort of question. It depends completely on your site - how big it is, how many users interact on it, how long it has been running, and when you last optimised it. However, the savings and speed-ups can be substantial; it is always worth making sure that your database is optimised.
In our support forum, here: https://wordpress.org/support/plugin/wp-optimize/
This is rare; it's probably because you're with a shared web hosting company that doesn't allow scripts to run an optimize command via SQL statements (SQL "OPTIMIZE" instruction). Please consult your web hosting company on this matter.
Yes - WP-Optimize Cache is WordPress's #1 most-installed optimisation plugin, with over 800,000 users and a pedigree going back over 8 years.
WP-Optimize will disable some features if it detects InnoDB tables. Optimization of the database tables on-disk is not available, but other clean up features would work.
Not unless you have an existing backup. Please ensure that you make a backup of your entire database before using WP-Optimize for the first time, and when you upgrade to a major new version of it. We recommend UpdraftPlus.
The plugin is an ongoing work; that means that it is impossible to rule out unforeseen situations and bugs. So I would recommend you to test it out on your local system or make a backup of your database (just to be extra careful).
When WordPress uses a particular transient, that specific transient is re-created automatically. So, it's normally for ones which are in active use to gradually re-appear. The best way to keep things optimal is to clear the transient options on a scheduled basis. For example, WordPress may create 50 transient option in a week. If you schedule WP-Optimize Cache to clear these options on a weekly basis, you'll have far fewer building up.
Please check your database for corrupted tables. That can happen, usually your web hosting company can run the repair command on the db.
To use all features in the plugin, a minimum of version WordPress 4.9 with PHP 7.2 are required. But we do recommend to use the latest version of WordPress. Using PHP 7.2+ is also highly recommended, as our caching feature will work even faster.
This depends on your setup (theme, number and quality of plugins used, etc...), but generally, caching will make the biggest visible difference to your website's performance. Indeed, the cache functionality bypasses most of WordPress code to serve your pre-optimised cached pages directly to your visitor, significantly increasing the speed.
"Caching", from Wikipedia: "In computing, a cache is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot." — WP-Optimize cache does this by saving the page computed by WordPress on the disk. When a user visits a page, WP-Optimize will serve the cached page before WordPress is loaded. If the page wasn't cached before, it will be computed by WordPress, and WP-Optimize will then save the result to the cache.
You think your site is fast without caching? A caching plugin will make your website even faster. A faster cached website will increase SEO, it will improve your visitors experience. Caching will also save your server's resources.
Yes, your Gutenberg pages will be cached, as well as those created with page builder plugins such as Elementor.
If cache is enabled, and in order to see if your page is cached, use the "View Source" function in your web browser to view the page source. To find caching information, scroll down to the bottom, and you should see a line added by the cache: <!-- Cached by WP Optimize - https://teamupdraft.com/wp-optimize/ - Last modified: Sat, 20 Jul 2019 21:17:19 GMT ->
However, note that if you are using a further service that minifies HTML (e.g. Cloudflare), then this line may have been removed. Another method is to inspect the contents of the directory wpo-cache inside your wp-content directory. <a href="https://teamupdraft.com/documentation/wp-optimize/topics/caching/faqs/how-do-i-know-my-webpage-is-being-cached/>Further information can be read here
Also note that if you do not preload the cache, a page or post will have to be visited once for the cache file to be generated.
Go to WP-Optimize -> Cache and enable caching. For most people, that will be enough. If you run an e-commerce, have a custom login page or any page that has dynamic content, you might want to exclude certain urls from the cache. Visit documentation for help.
Yes, caching with WP-Optimize Cache allows you to safely cache your products, with plugins like WooCommerce or Easy Digital Downloads, or any e-commerce that uses DONOTCACHEPAGE to exclude sensitive pages from caching (e.g. my account, cart or checkout pages).
Yes, WP-Optimize works with popular multilingual plugins like WPML or Polylang. However, it's important to note that when using WP-Optimize with multilingual plugins, the URL format for different languages should not include any query parameters, for example https://example.com/?lang=en. Instead, it should be in a pretty permalink format, such as https://example.com/en.
No, if WordPress works properly, WP-Optimize will be able to cache your pages and posts.
No, because both cache plugins would need to use the drop-in plugin advanced-cache.php. If you turn off caching on WP-Optimize Cache, you can use any other caching plugin and still use the other features of WP-Optimize. But we do recommend using our caching solution.
Yes! No special cache configuration is needed. Page caching on the WP site (that done by WP-Optimize Cache) is independent of proxy caching (e.g. Cloudflare) – you can use both, or neither, and they will complement each other and not interfere. Just one thing to note – Cloudflare will strip out the special HTML comment at the bottom of the source of a page that is helpful to confirm that page caching is working, so, don't be confused by that – it's absence doesn't indicate the cache is not working.
Yes, you can trigger a cache purge action using WP-Optimize Cache public functions. If you want to clear the whole cache, use the function wpo_cache_flush(). If you want to clear the cache files for a specific page or post, use WPO_Page_Cache::delete_single_post_cache($post_id);. Those cache options are available after WP action plugins_loaded.
Yes, when using WordPress' commenting system, your users will still be able to post comments. Every time a comment is approved, the cache for that page or post will be cleared, allowing the next visitor to see an up to date list of comments.
Usually, a page is cached when a user visits it. So the first user visiting won't be served a cached version of the page, and will wait longer than the next users. The cache preloading functionality will go through all your pages and posts, and simulate a visit by a user, allowing WP-Optimize to cache the pages before anyone visits them. Your first visitor will thus be served a cached version of the page, increasing its performance.
Choosing a frequency for the cache preloading schedule will depend on factors such as the frequency at which the website content is updated, the number of pages in the cache, the resources of the server and more. For example a site with hundreds of pages will require more resources to preload its cache. So choosing a high frequency will mean that the cache will be recreated often, and the resource usage will be higher. On a website where updates aren't as frequent, you can even disable the cache preloading schedule, or set a high cache lifespan and set the cache preloading schedule to follow it.
Add /.+ to the cache option "URLs to exclude from cache" on the advanced settings tab.
To prevent a page from being cached, you can add the URL to the field "URLs to exclude from cache" in the cache "Advanced settings" tab. If you are developing a plugin and want to prevent a page from being cached, you can define the "DONOTCACHEPAGE" constant on the pages you need. Any request where "DONOTCACHEPAGE" is defined will not be cached.
Yes the caching feature is free. You will always be able to cache your website for free using WP-Optimize and we are constantly working on improving the existing cache feature. We will add more caching options to the free version and develop more specific caching options in the premium version to enable you to taylor the caching functionality to your needs.
The cached files are stored in the common "wp-content/cache" folder, inside a "wpo-cache" folder. Removing the "cache" folder will delete all of WP-Optimize's cache, as well as those from other plugins. Deleting the "cache" folder is generally safe, as those cached files will be regenerated.
Go to WP-Optimize settings > Cache and toggle the "Enable page caching" option to on/off.
No, caching will actually reduce the load on your server, by reducing the amount of PHP and mysql used. You might see a peak in resource usage when using the cache preloader, as this functionality will create the cache files for all your pages in a short amount of time. But once this is done, performance should increase and the load on your server will decrease. Every single major site uses caching to serve cached pages faster by using fewer resources.
The cached page is sent to the user before most of WordPress was loaded. The plugins aren't loaded yet, making it impossible for them to change the cached content at every request. So at the moment if you want to keep parts of your page dynamic (e.g. adverts, widgets, shopping cart...) AND keep it cached, you will have to use custom solutions using javascript and AJAX to fetch those dynamic parts from the server.
WP-Optimize Cache will remove the "WP_CACHE" constant from wp-config.php when you disable page caching, or when you deactivate the cache plugin. If you need to remove it manually, you can use FTP to edit wp-config.php and delete the line define ('WP_CACHE', true ); If page caching is still enabled in the settings, WP-Optimize Cache will attempt to add the line again, as it is required for the caching functionality to work.
WP-Optimize caching feature needs write access to the 'wp-content/cache' folder, as this is where the cache files will be stored. It also needs to define the constant 'WP_CACHE' in 'wp-config.php', it will need access once to 'wp-content/advanced-cache.php', as well as to the folder 'wp-content/wpo-cache' to write the cache settings.
If you need to change file permissions to enable caching, you can follow the instructions on this page https://wordpress.org/support/article/changing-file-permissions/
There is no limit to the number of pages you can cache. The only limit is the space on your server and the maximum number of subdirectories allowed by your server, as caching will write files in subdirectories following the permalink structure. If you were to reach a caching limit, it probably means that your server is not fit for the size of your website and caching needs.
You can generate a separate cache by selecting "Generate separate files for mobile devices" in the page cache settings. This cache setting is only necessary if you use a specific theme for mobile devices, or for certain AMP plugins.
Yes, the cache feature works with Nginx. Should you want to enable browser caching or GZIP compression, you will have to do this yourself directly on the server settings.
Yes, the cache feature works with
