After Kernel-Update no login via login.php3 and changes in PLESK are not saved!

Hi all,
I've got the following problem:
After Kernel-Update no login via https://<MYSERVER>.stratoserver.net:8443/login.php3 and changes in PLESK are not saved!

My System:
OS: SuSE 11.1
Plesk-Version: 9.2.2
Kernel-Version: 2.6.27.29


I did the following steps:
1.) Kernel-Update using yast, than reboot -> drweb-daemon don't start -> ok, but login in PLESK works fine!
2.) change /usr/local/psa/admin/conf/php.ini 2MByte to 10MByte Post and Upload Size -> restart PLESK-Services "service psa stopall" -> "service psa start" (only drwebd did not start)
3.) try to login to PLESK - this don't work! -> try login https://<MYSERVER>.stratoserver.net:8443/login_up.php3?login_name=admin&passwd=<PASSWORD> works fine -> BUT: any changes aren't saved!

Checking PSA-Logfiles with no results.
(/usr/local/psa/var/log -> just maillogs,
/usr/local/psa/admin/logs -> httpsd access logs)

Do you have any suggestions to solve this issue(no "normal login", no saving of changes)?

Regards,
