Lost php color syntax and code navigation after upgrade

Today I upgraded my IntelliJ IDEA from 10 to 11

The problem now is that I lost color syntax for my php files and I can't navigate or refactor my php source code anymore.
I already tried to delete my Java based module(only option I had in 10 and worked perfectly) and create a webmodule but nothing changes.

Can anyone please tell me how to fix this ASAP so I can code again (with pleasure)
