 * Every single time I update Clearfy, my site stops operating for 30-60 seconds
   and I get an email saying
 * “Since WordPress 5.2 there is a built-in feature that detects when a plugin or
   theme causes a fatal error on your site, and notifies you with this automated
   email.
 * In this case, WordPress caught an error with one of your plugins, Webcraftic 
   Clearfy – WordPress optimization plugin.”
 * but then the plugin is actually working fine. Clearly a wordpress bug but perhaps
   something this plugin is not adhering to with WordPress’ new “Auto Detection”
   nonsense.

 * Hello.
 * To understand what happened, we need to look at the errors. To do this, enable
   debug mode – add these lines to the **wp-config.php** file:
 *     ```
       define( 'WP_DEBUG', true ); 
       define( 'WP_DEBUG_LOG', true );
       define( 'WP_DEBUG_DISPLAY', false );
       ```
   
 * After that, update the Clearly. After that, you can disable debugging mode.
    
   Error messages will appear in the **wp-content/debug.log** file. Send them all
   here
