Specify a custom cache folder and config path

Specify custom cache colder

By default, WP Rocket creates folders for the cache and other optimized files in:

/wp-content/cache/

It's possible to specify a custom location by defining the following constants in wp-config.php:

• WP_ROCKET_CACHE_ROOT_PATH to specify the absolute cache folder path
• WP_ROCKET_CACHE_ROOT_URL to specify the cache folder URL

For example:

define( 'WP_ROCKET_CACHE_ROOT_PATH', $_SERVER['DOCUMENT_ROOT'] . '/new-path/cache/' );
define( 'WP_ROCKET_CACHE_ROOT_URL', 'https://example.com/new-path/cache/' );

Specify custom config location

It's also possible to specify a custom location for WP Rocket's configuration file, which is, by default, saved in:
/wp-content/wp-rocket-config/

To do so, you should define the following constant in the wp-config.php:

• WP_ROCKET_CONFIG_PATH

For example:

define( 'WP_ROCKET_CONFIG_PATH', $_SERVER['DOCUMENT_ROOT'] . '/new-path/' );

⚠️ Important: If you change WP_ROCKET_CONFIG_PATH, the new folder cannot be a shared directory, only WP Rocket's files should be present in this directory.

After defining a custom cache folder and / or a custom configuration folder, you also need to: 

• Deactivate / reactivate WP Rocket to update the advanced-cache.php file and htaccess file accordingly and recreate the configuration file in the new location. 
• Delete old wp-content/cache folders manually via FTP (wp-rocket, min, busting, critical-css)
• Regenerate your Critical Path CSS (if Load CSS Asynchronously is enabled)
• If you use this NGINX configuration, you will have to edit the paths that are hard-coded there.
