 * So it was detected before, and now it’s not detected anymore. I’m running Apache
   with Zend Opcache and PHP-memcache
 * The compatability check says it’s not found.
 *     ```
       php -r 'phpinfo();' | grep -i 'memca'
       memcache
       memcache support => enabled
       memcache.allow_failover => 1 => 1
       memcache.chunk_size => 8192 => 8192
       memcache.default_port => 11211 => 11211
       memcache.default_timeout_ms => 1000 => 1000
       memcache.hash_function => crc32 => crc32
       memcache.hash_strategy => standard => standard
       memcache.max_failover_attempts => 20 => 20
       Registered save handlers => files user memcache
       ```

    I can seee memcached running in my htop viewer as well.
 * I removed all my plugins and reinstalled w3-total-cache. It then said there was
   a critical error with memcached. I renamed the config file in the wp-content/
   cache/w3-total-cache/master.php. I don’t see it anymore though, that folder has
   disappeared. I’d like to get memcache back online, so let me know if anything
   else could be helpful. Thanks!
