# Cannot Save Settings for Database Cache

 * I’m having a strange issue with the plugin. I have had uninstall and reinstalled
   the plugin a few times trying to sort out permission issues on my server. I have
   since corrected this issue and was getting back to configuring the total cache
   plugin and everything seemed to be going well until I enabled the database cache.
   I can enable the database cache with the memcache option just fine from the general
   settings page but when I got to edit the specific settings for the database cache
   and save them. I get redirected to my home screen. The setting I’m trying to 
   change is Memcached hostname:port / IP:port: I have also noticed it doesn’t matter
   if change anything or not in the database cache settings just clicking the save
   button causes this behavior. I have removed and added the plugin back in a few
   times but I cannot seem to get this to work. It should also be noted I don’t 
   have any issue adjusting this settings on any of the other areas i.e. page cache,
   object cache…. any help on this would be helpful.I have attempted to remove all
   traces of the plugin manually but I believe this is not working as I’m either
   missing files that need to be deleted or there is data in the database that needs
   to removed as well. I am also running the latest version of this plugin.

 * Further update on this issue it seems to be related to the default values in 
   the Ignored query stems:
 * I have the following defaults
 * gdsr_
    wp_rg_ _wp_session_
 * If either wp_rg_ or _wp_session_ is in the list the plugin will not save the 
   settings if I remove them and only have gdsr_ or nothing at all the settings 
   save just fine.
