PLESK Firewall "Apply Configuration" problem

[AlkatraZ]

Server Information
Version: Parallels Plesk Panel v11.0.9_build110120608.15 os_SuSE 12.1
OS: openSUSE 12.1

When you try to activate the new configuration PLESK Firewall, the following error occurs:

Error: Another administrator is activating a configuration now.

The bug only occurred after Microupdate at Sept 3, 2012.
Before that everything worked fine.
Attempt to restart the PLESK does not help.

How can you fix it?
I would be grateful for your help.

"Another administrator is activating a configuration now." error appears when previous activation task wasn't completed correct.
When activation task is started it creates "safeact.confirm" file in "/usr/local/psa/var/modules/firewall" directory to prevent duplicate firewall configuring task. And after activation finished that file removed. By some reason "safeact.confirm" was not deleted and when you tried to start new activation task it provided an error.

"safeact.confirm" file in "/usr/local/psa/var/modules/firewall"

Thank you very much!
I deleted this file and the problem was solved.
