CMS Home messed up
 

Hi there, everything was going fine on my forums, suddenly the "Home page" decided to:

-remove my logo and put back the bulletin logo.
-it removed the background of my page and all the frames and left the text only.

and for some reason I found a google search bar that I don't even know how to install in the first place to get rid of...

Aliens maybe? lol j/k.

The Q is, how to I reset the home page or even the whole forum without losing my media, users etc. ?
