Resolved Nextcloud Problems after restoring Backup

Hi all!

After i restored a backup to my new virtual server installation i encountered a problem with Nextcloud. The configured subdomain was restored, the content was copied properly but when i try to access the site i get:

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

But nothing in Apaches Server Logs. Next i looked at the Dashboard of the Subdomain, but when i click at "Nextcloud" i get a blank Page displaying shortly something like "Finding existing Instances". So i assume theres something wrong with the Extension. I havent found an Option to repair the Extension, only install, uninstall it.
Is there a way to get Nextcloud Extension working again?

Thx for help in advance

I found a solution for my error. it was the apcu module in php that was not installed liked in my config:

 ...
 'memcache.local' => '\\OC\\Memcache\\APCu',
 ...

After installing and configuring this module everything runs as it should!

thx
