mod_fcgid: error reading data from FastCGI server ,End of script output before headers: index.php

Hi All,

Since last night when a kernel update was done on my Virtualmin pro server nothing with php will start.

Operating system Ubuntu Linux 14.04
Kernel and CPU Linux 3.13.0-30-generic on x86_64

on the website i get "
Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at xxxxx@xxx.com to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

in the error log I get, :
[fcgid:warn] [pid 3718] (104)Connection reset by peer: [client xxxxxxxxx] mod_fcgid: error reading data from FastCGI server
[Tue Jul 15 07:56:35.353379 2014] [core:error] [pid 3718] [client xxxxxxx:53787] End of script output before headers: index.php

At first I got a lot off errors on the apache2 config files those were fixed and apache started as well as Mysql, but now I got stuck…

anyone?
