Error 502 after manual update

[Steve1980]

Hi all,

After a failed automatic upgrade I manually updated plesk via the upgrades and components page.

I am now unable to log into the Plesk control panel however all the websites are still working (thank God).

Does anyone know what the issue can be? I am running Centos 6 and Plesk 12.

I've really don't want to reinstall Plesk as I will lose everything.

The SW Engine had stopped. Restarted that and now all working.
