There may be something broken there.

Edit wp-admin/index.php and under the line `require_once __DIR__ . '/admin.php';` add this temporarily: * `wp_mail( "your email", "DEBUG: cache path", "cache path: " . $cache_path );` * Change “your email” to your own email address. And then load your dashboard. You should be sent an email with the cache path in it. Make sure to undo and save wp-admin/index.php again as you will get an email every time someone loads the dashboard. * Do you see “cache path: /x/y/z/cache/” where /x/y/z/ is the path to where you have the cache directory? Or do you only see “cache path:” ? * What you’re seeing leads me to believe your configuration somehow got corrupted and the path to the cache directory has been overwritten. * Plugin Author [Donncha O Caoimh (a11n)](https://wordpress.org/support/users/donncha/) * (@donncha) * [4 years, 6 months ago](https://wordpress.org/support/topic/open_basedir-restriction-5/#post-15152413) * If you try the development version of the plugin which you can find on the following page, you’ll be shown an error as a HTML comment at the end of any page if the plugin detects a broken configuration. * [http://odd.blog/y/2o](http://odd.blog/y/2o) * The error is “WARNING! Caching disabled. Configuration corrupted. Reset configuration on Advanced Settings page.” * If you get that warning, take a look at wp-content/wp-cache-config.php * Here’s a sample config file that should look similar to what your config file looks like for comparison.

Is that what $cache_path was when the WARNING text was shown in the HTML of your website? Or is it what it normally is?
