Okay so I installed http://xenforo.com/community/resources/last-post-avatar-by-waindigo-win-edition.266/ And every page displays this. An unexpected error occurred. Please try again later. So I went to install to rebuild caches, and i have to login. So it goes to /admin.php?login/login and it says the error. So i can't do anything about it!!! I need help!
