If you can't resolve the issue on your own, please address Parallels support.

When i try to go to the plesk panel it shows a 502 error site and the service sw-cp-server isnt able to get started.

Can anybody help me?

What the heck... i found the solution by myself...

i was reading in psa_service log:

Starting sw-engine-fpm: [23-Sep-2018 15:11:14] ERROR: failed to open error_log (/var/log/sw-cp-server/sw-engine.log): No such file or directory (2)
[23-Sep-2018 15:11:14] ERROR: failed to post process the configuration
[23-Sep-2018 15:11:14] ERROR: FPM initialization failed

so i recreated the folder sw-cp-server folder which was deleted as i tried to free a bit of disk space weeks before... so plesk couldnt work if you delete the log-file folders.... puh... maybe somebody should take off this dependency.... or i should watch out next time deleting files...
