[BlueOnyx:08977] Problem with php-sessions after updates

[Klein Joachim]

Hy to the list!

After the updates from 4. november I have problems with none working 
sessions
in Php.
I have tried a test script (one script initalize the session and the 
second should read it), but
the don´t work.
Also none session file is written in the directory /var/lib/php/sessions

The only parameter which is different from a working installation on 
Blueonyx:
None working Server
session.use_only_cookies On On

Working server
session.use_only_cookies Off Off

But I can´t change the corresponting php.ini file in the /home/sites.... 
Folder.
I get the error message permission denied, also as root-user.
