Had the same problem after installing a Plug in then removing it. Even Removed the Plug in from my C-Panel (FTP) and it started giving me those funny messages.
So I added a little line in my Htacess code:
AddType x-mapp-php5 .php
strange everything went back to normal.
I use 1 & 1 hosting.

Got it thanks!
