Plesk error: Class Limits_Limit_Base

[Tom_Sebrechts]

Since this morning I have an issue with Plesk...

When I try to login I get this error:

ERROR: Class Limits_Limit_Base contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Limits_Limit_Interface::setBackendSubscriptionLimitValue) (Base.php:353)

I don't know how this happend and when this exactly happend...
I didn't update or upgrade anything and Plesk was working fine untill about 3 this morning...

I run a Windows 2012 server with Plesk 12.

Can anyone help me with this?

I have resolved the above problem partly, I guess...

This is the problem from the error-log:

Execution failed.
Command: ai.exe
Arguments: Array
(
[0] => --select-product-id
[1] => panel
[2] => --select-release-current
[3] => --upgrade-installed-components
)

Details: ERROR: can't apply patch panel-12.0.18~patch40

If you cannot resolve the issue on your own, contact product technical support for assistance.

I did the file renaming manually and that gave me access back to the control panel. But now I have an error-message at the top of my control panel screen that says that the last update failed.
I cannot find a way to try and update again. Can someone help me out with this please?

I have the same problem. The system is Windows Web server 2008 R2. I have no access to domains and subscriptions in control panel of Plesk after upgrade to version 12.0.18. The command %plesk_dir%\admin\bin\ai.exe --select-product-id panel --select-release-current --reinstall-patch --install-component base return the error "
ERROR: can't apply patch panel-12.0.18~patch44

Warning! Not all packages were installed."
This happens again and again each time I run the command with other folders as ...\admin\plib and so on. Can you help me?
