WP Cache Plugin Deletes itself

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.

    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. 🙂

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.
