class.ActionLog.php is damaged

[slotty2k]

Hi,

after a failed update from Plesk 7.5.4 to 8.0 and some problems I reinstalled Plesk 7.5.4.
Everything seems to work now fine again, only when I did some actions (like login or starting/stopping a service) a blank page appeared.
I read, that I should enable the php error messages and I did so. Now the following message appears:

Fatal error: File is damaged, please reinstall in /usr/local/psa/admin/plib/class.ActionLog.php on line 476

Any ideas how to fix it? I didn't find anything with google. Reinstalling the main Plesk-RPM didn't change anything.
