 * Hello,
    Each time I enable Memcache from the SiteGround Cpanel and in my admin
   area for [http://yourtechadvisors.com](http://yourtechadvisors.com), the site
   throws timeout errors on the front and back end of the site. I received this 
   reply from a ticket on SiteGround.

 * I have tried deactivating all plugins, deactivating mu-plugins, installing the
   latest version of the plugin again, and installing WordPress again.
 * Any ideas?
 * Thanks.

 * I have experienced a very similar issue. Sometimes “killing” Memcached from active
   processes helps to solve the issue.
 * It would be great if SiteGround would look into this issue more carefully. As
   it is now Memcached is causing random timeouts (504 errors / 522 errors – through
   CloudFlare).
 * Any recommendations beyond just disabling Memcached would be greatly appreciated
   from a fellow SG customer 🙂

 * How do you do that? After I disable Memcache in Cpanel, I have to go delete the
   cache file in wp-content to, if I do not delete that file, the site will not 
   load.
 * I also uncovered another error.
    `[23-Mar-2016 22:39:51 UTC] PHP Warning: Cannot
   modify header information - headers already sent by (output started at /home/
   ytadvise/public_html/wp-includes/functions.php:3792) in /home/ytadvise/public_html/

 * Thanks.

 * Hello,
    It is all fixed, there were some database tables that were to big and
   that was causing the timeout. Deleted the tables and everything is working fine
   with Memcache.
 * Thanks.
