Plesk 500 Error On Admin login

[YasinA]

Hello

I have a trouble with the 10.4.4 version and it started after the upgrade, when i try to login as admin i get the 500 server error but users not getting this, in the logs it says

6-Jun-2012 13:32:48] PHP Fatal error: Call to undefined function defpackagemngMaker() in C:\Program Files (x86)\Parallels\Plesk\admin\htdocs\index.php on line 24

Is there a way to fix this? Any help will be appreciated.

Funny,

Started happening to several persons at once.

This is exactly what is happening to my server since yesterday with no aparent reason.

I did not even do any windows update lately (just to blame windows

however my plesk installation is with automatic updates enabled so I could blame parallels

Any way to fix this?

On application pools pleskpanel shows stopped and when I restart, still get the 503 error

Please look at closely my error is 500 error and occurs only for index.php , all other subpages working and also customers can enter to the panel, just admin cannot enter.
