 * Hi, the plugin is really great, but I have some issue with disabling plugins.
 * Not related: APCu php extension for object caching is now disabled, because I
   have another issue with object caching.
 * I was using it alongside WP Fastest cache for testing for the last hours. 
   I 
   tried to disable WP Fastest cache, but it caused Fatal error. Next I tried to
   disable any plugin and got the same error.

 * Hello, 
   Do not use multiple page cache plugins simultaneously.That will mix things
   up, guaranteed.
 * If you have APCu enabled and activate atec-cache-apcu, object-cache.php file 
   will be installed, which depends on APCu. 
   If afterwards you disable APCu without
   disabling atec-cache-apcu, the object-cache.php stays installed, but can not 
   work, because APCu is missing.Keep in mind that atec-cache-apcu enables object
   caching. Page caching is an add on, but two different shoes.

 * I guessed that. Yes I use only page caching. It’s great for now.
 * But the error is I cannot disable or update **any** plugin. Fastest cache is 
   just an example.
   Anyways I will try manually remove and reinstall the plugin 
   and see if it happens again.

 * You can use the APCu object-cache together with a page cache plugin but not two
   page-cache plugins at the same time.

 * atec-cache-apcu page caching does not come without object-cache.
   it is installed
   on activation.if you do not want object-cache, you can try wpmegacache.comfor
   the plugin issue, flush the WP object-cache to update the “installed” status.
   that is a known issue with persistent oc.

 * If you expierence issues with the latest update v2.1.84, please rename or delete
   the file /wp-content/object-cache.php, reload and enable object caching again.
 * This should solve the issue.
