Cannot Create the Cache Directory ... or It Is Not Writable

Problem

You receive an error message indicating that the cache directory cannot be created or is not writable.

 

Cause

The WP Cloud plugins store cache data in the /wp-content/[WP Cloud Plugin Name]-cache/ folder. For the plugin to function properly, this folder must exist and be writable. This error occurs when the plugin cannot create the cache folder or when the folder is not writable. Usually, the plugin should resolve this automatically, but server file/folder permissions may not be set to the default WordPress values, preventing the necessary changes.

 

Solution

  1. Update Folder Permissions
    Navigate to the /wp-content/[WP Cloud Plugin Name]-cache/ folder via FTP and update the folder permissions to 755.

    • If the permissions are already set to 755, try manually copying the contents of the /wp-content/plugins/[WP Cloud Plugin Name]/cache/ folder into the /wp-content/[WP Cloud Plugin Name]-cache/ folder.

  2. Solution 2: Define a Custom Cache Folder Location
    You can define your own cache folder location for the plugin by adding the following lines to your wp-config.php file:

    define('[PLUGIN_SLUG]_CACHEDIR', WP_CONTENT_DIR.'/uploads/[PLUGIN_SLUG]-cache/');
    define('[PLUGIN_SLUG]_CACHEURL', content_url().'/uploads/[PLUGIN_SLUG]-cache/');
