Installing WP-Optimize Premium
- Download the WP-Optimize Premium from the link in your confirmation email, or from your account page here.
- After downloading the file, log in to your WP admin dashboard, then go to Plugins->Add New
- …and then press the “Upload Plugin” button near the title at the top of the page… N.B. If your web hosting is configured with a small maximum upload limit, and WordPress says that the plugin could not be uploaded because it was too big, then you can first install this plugin, which extends WordPress’s plugin uploader with the ability to handle files above the configured PHP upload limit. Alternatively, you can install it manually instead: i.e., 1) Unzip the zip file on your computer 2) Use FTP to transfer the resulting directory “wp-optimize-premium” into wp-content/plugins (so that it becomes wp-content/plugins/wp-optimize-premium).
- After the plugin has uploaded, press the link to activate WP-Optimize Premium.
- If you have the free version of WP-Optimize already installed on your website, you don’t need to worry about anything as it will be automatically deactivated. You also will not need to install the free version to make WP-Optimize Premium run.

Caching your site
To enable page caching, go to WP Admin Panel » WP-Optimize » Cache. Enable caching, and save the settings.
That’s it! Your pages will start to cache.
Advanced caching options
Advanced settings – exclude URLs
To excude an URL from your cache, add its path to the “List URLs that should not be cached” field. Eg. if you want to exclude
Use of wildcards:
You can use * wildcards to match several pages. For example,
/shop/* will exclude all pages with /shop at the beginning of their path. You can also use 2
* to exclude a page containing a string anywhere in its path. Eg. entering
*shop* will exclude
http://my-website.com/shop as well as
Extending the page cache
Adding custom cache extensions
- First, choose a location to store your code. Set the constant WPO_CACHE_CUSTOM_EXT_DIR in your site’s wp-config.php. For example:
define( 'WPO_CACHE_CUSTOM_EXT_DIR', ABSPATH . '/path/to/cache/extensions' );
- Create a php file in this location, and add your code.
- If you have the premium version, you can look in wp-optimize/cache/extensions for examples.
Overriding existing extensions
If your version of WP-Optimize comes with bundled extensions, you can override them. To do so, you need to copy them somewhere outside of WP-Optimize’s folder, to prevent them from being overridden when updating the plugin:
- Copy the folder wp-optimize/cache/extensions to a custom location
- In your site’s wp-config.php, define the constant WPO_CACHE_EXT_DIR with the folder you chose to copy the default extensions to. For example:
define( 'WPO_CACHE_EXT_DIR', ABSPATH . '/path/to/default/cache/extensions' );
- There you can override the extensions, and your changes will be kept when WP-Optimize will be updated.
- You can also add your own extensions in this folder, without the need to use the extra WPO_CACHE_CUSTOM_EXT_DIR method.
Purging the cache from an other plugin or theme
You can trigger a cache purge using WP-Optimize public functions.
WP_Optimize()->get_page_cache()->purge(); to flush the whole cache.
WPO_Page_Cache::delete_single_post_cache($post_id); to purge a single post’s files.
Those cache options are available from WordPress action
