Hi everyone,

after a restore (comlpete server) I can´t access plesk via the GUI. I tried to run plesk repair via ssh but unfortunately only got the following error message:

PHP Warning: require(/opt/psa/admin/plib/vendor/composer/../laminas/laminas-servicemanager/src/autoload.php): Failed to open stream: No such file or directory in /opt/psa/admin/plib/vendor/composer/autoload_real.php on line 45

Does anyone have an idea how to solve the problem?
Thanks in advance for any help!

When trying to log in to Plesk via SSH, the same error message appears ...

I guess the first question I have is how was the restore done? Was it a full VM restore, bare metal? OS level restore? Files only?

In either case, you tried running the following in a SSH session?

plesk repair installation

If that didn't work, try reinstalling by following the instructions at Quick Start

Thank you for your reply. The restore was performed for our entire VM, I mean with Arconis (I only see BackupControl in the hoster's backend).

plesk repair installation

I tried, unfortunately the same error message

If I reinstall Plesk, won't the data be lost?

No it doesn't touch the existing files and should reconfigure everything.

OK, thanks!
I entered "plesk installer" and unfortunately the error message came up again. Should I continue anyway?

Proceeding with installation or upgrade without resolving the issues
that were found can corrupt your data.

Do you want to continue? [y/n]:
