 * Hi, I have been using the Super Cache plugin for many years without any problems.
   However over the past month, the plugin has Deleted itself from my website on
   its own?? I cant see any logical reasons why this would happen and would love
   to know what is causing the issue.
 * We do also have **W3Speedster Pro** installed, however they have always worked
   well together up until recently.
 * Any help would be greatly appreciated.
 * Are there any log files I could look at to find more details on this,

 * I downloaded W3Speedster and found that it checks if this plugin is active and
   recommends it be deactivated, and it then deletes this plugins’s config file.
 *     ```wp-block-code
           function w3_check_super_cache($path, $htaccess){
               if($this->w3_is_plugin_active('wp-super-cache/wp-cache.php')){
                   return array("WP Super Cache needs to be deactive", "error");
               }else{
                   @unlink($path."wp-content/wp-cache-config.php");
   
                   $message = "";
   
                   if(is_file($path."wp-content/wp-cache-config.php")){
                       $message .= "<br>- be sure that you removed /wp-content/wp-cache-config.php";
                   }
   
                   if(preg_match("/supercache/", $htaccess)){
                       $message .= "<br>- be sure that you removed the rules of super cache from the .htaccess";
                   }
   
                   return $message ? array("WP Super Cache cannot remove its own remnants so please follow the steps below".$message, "error") : "";
               }
   
               return "";
           }
       ```
   
 * I don’t know if the PRO version deletes the action plugins/wp-super-cache folder,
   but this one definitely deletes the config file, which is a bit much.
 * I’d recommend Jetpack Boost which does a similar job and does work well with 
   this plugin. I work on Boost too, so I would suggest that, of course. 🙂

 * Thank you for looking into this Donncha, it is greatly appreciated.
 * It turns out that WP Engine, the WordPress hosting provider, has been deleting
   the Cache plugin as they have it on there Blacklist of plugins.
 * Here is an extract:
 * Caching Plugins
 * Caching plugins can conflict with our platform’s built-in caching structure. 
   These plugins are known to cause direct conflicts and would ultimately impact
   your site’s ability to load if used:
    - **WP Super Cache**
    - **WP File Cache**
    - **W3 Total Cache**
 * Many of the caching features these plugins offer we have built-in to our servers
   by default as part of your managed WordPress hosting experience. We have your
   back- don’t worry!
 * More can be viewed on the [WP Engine Support page here](https://wpengine.com/support/disallowed-plugins/)
 * I am currently working on applying another WP cache fix for the website as the
   server side Cache services are not adequate in achieving good Google core metrics.

 * Ah, that makes sense. Glad you found out what caused it. Give Boost a go. The
   free version is very generous in what it does and may suit your needs.
