Login Issue (corrupted PHP environment?)

[gnetix]

Hi,

We done a few modifications on the php.ini files today and by mistake i think we modified the one dedicated to the Plesk CP (located in the /admin folder).

Even after restoring the original file, i have the following error message on CP login :

The file index.php is part of Plesk distribution. It cannot be run outside of Plesk environment.

I noticed the following KB article :

I have done the second fix (switching web server), without any result. It cant be related to the license, it was working fine prior to that php.ini thing...

I also tried to "Repair" Plesk (Control Panel / Add & Remove Software) but im having Fatal error during installation.

Any help would be greatly appreciated.

Thanks you very much.
