 * I made a number of changes to an organization’s website today and then went to
   active the Optimize Database after Deleting Revisions plugin, however, the screen
   just refreshes and the plugin remains deactivated. We’ve used it for several 
   years with the website in question and never had a single issue.
 * WordPress and all plugins are regularly updated. Plus we only keep necessary 
   plugins activate 24/7, and just activate others as we need to during site maintenance
   and updates.
 * Any clue why the plugin is suddenly being so shy?

 * Hey,
 * Did you try to (temporarily) de-activate all other plugins?

 * With 16 active plugins, I decided to try disabling the plugins one by one and
   seeing which one was messing with the Optimize DB plugin. Got lucky on the very
   first one. Appears that the Varnish plugin is the culprit.
 * Thanks for the help!
