# Installing plugin caused "500 server error"

 * I installed your plugin via the plugin manager in WordPress. Upon activation,
   I went to the page setup section of the plugin. I clicked on “Edit” for the default“
   Home” page. I received a 404 error. Subsequently, upon trying to re-access wp-
   admin, my site was 500.
 * Please, is there any way you can help?
 * My most recent viable backup is from 8/29/2012 and I’d prefer to not need to 
   recover.

 * I installed your plugin a few moments ago and now my site is down! I have also
   gotten both types of errors 404 and now 500. I can’t seem to get it back. If 
   I delete the plugin folder from the server will this bring my site back up? This
   is frustrating!

 * Thanks for the feedback. First I would check the minimum requirements.
 * **Minimum Requirements**
    WordPress 3.5 PHP version 5.3 or greater MySQL version
   5.5 or greater
 * if all of those check out then we have a problem. I try hard to break the plugin
   when I develop so your input is helpful. If you have any more useful information
   I would appreciate it.

 * For my site, I found that MobileChief changed my .htaccess rules which conflicted
   with W3TotalCache. I had to wipe out .htaccess and rebuild from scratch to make
   my site function again.
