 * personally i really dislike the ‘one plugin does it all’ approach because this
   virtually always leads to it doing nothing well – adding page caching is outside
   the scope of this plugin IMO and so i’ll be dumping it
 * after activating the cache to check something, then immediately deactivating 
   it, WordPress is left with a permanent “// WP-Optimize: page cache disabled” 
   in the backend, even when the plugin is disabled, and even after it has been 
   deleted
 * really?
 * and now my proper caching plugin, LiteSpeed cache, is reporting that “LiteSpeed
   has detected another plugin using the “Advanced Cache” file.”, again, even after
   WP-Optimize was deleted
 * and so now i have to clean up the mess it left behind
 * unreal

 * Did this get resolved? I just disabled the cache and deleted it and now have
   //
   WP-Optimize: page cache disabled
 * displayed on my banner. Restoring old databases isn’t resolving it

 * in /wp-content see if there are 2 advanced-cache.php files, one with a .bak extension–
   if so, rename the current one (add .old or whatever) and then remove .bak from
   the other and see if that works
 * if you did not have a caching plugin installed, there may not be an advanced-
   cache.php.bak – in that case i think you can just delete the `// WP-Optimize:
   page cache disabled` string from the one you named .old, then just remove the.
   old extension and you should be good
 * appears the developers never bothered to test this very well which is another
   reason i removed this plugin

 * Thank you for the report. Please:
 * – update to version 3.0.1
 * – then turn the page cache on and then off again; or alternatively, just delete
   the file wp-content/advanced-cache.php
 * You must do the second step, not just the first. Sorry for the inconvenience!
 * I’ll try not to bore with too many technical details, but, in theory this bug
   should have been impossible to occur – it requires `WP_CACHE` to be set to `true`
   by something; but that something has not taken control of `advanced-cache.php`
   as it should do when setting `WP_CACHE` to true. i.e. The occurrence of this 
   bug indicates some other underlying anomaly in the WP installs it occurred on.

   hours of searching

 * I agree with the OP, I really liked this plugin for specific DB optimization.
   Now it’s got all this other stuff I don’t want junking up my sites. And some 
   of them after this update are now getting a pop up error stating “an unexpected
   response was received” whenever I load any of the WP-Optimize setting pages on
   the back end. Messy.

 * > I really liked this plugin for specific DB optimization
 * actually it’s not even great at that – after dumping WP-O i installed Plugins
   Garbage Collector and it found a bunch of db tables that were left by 4 plugins
   i uninstalled long ago
