Thank you Patrick,

I just looked at my phpinfo, to know what modules are running. First  
on our server we have Apache/2.0.54 (Debian GNU/Linux) PHP/5.2.3 with  
Suhosin-Patch DAV/2. The mod_security module is not activated.  
However, I don't think that the problem is mod_security because as  
mentioned on the troubleshooting page I should get an Errormessage  
from the server. Instead of this i get no error message. The page is  
loading but with out saving the new changes (the additional lines).

I tried the second also, without any results.  
ini_set('pcre.backtrack_limit', 1000000); was already set in the  
config.php. Adding the second line changed nothing.

Still a little confused...
