 * You just answered your own question. Disable the Events Manager plugin. You may
   not want to use that plugin anyway: there’s a documented XSS attack against version
   3.1.2 of Events Manager Extended.

 * Sofaking,
 * I can’t even get to my back office now. That message shows up on my blog site
   as well as admin area. Any ideas?

 * FTP in and move or remove the folder that contains that plugin.

 * _DO NOT MAKE MULTIPLE POSTS LIKE THIS_
 * And ask your webhost if you don’t know how to FTP to their server.
