File Sharing not working after migration from OwnCloud (9.4) to Nextcloud (10.0)

Hello,

after migration from OwnCloud (9.4) to Nextcloud (10.0) I can not access next cloud anymore, if files sharing is enabled.

nextcloud.log

Does anyone have a solution for this error?

Thx

Do you mean the file-sharing app? Once it is enabled, you get this error?

Can you check on the webinterface on your admin page, if the code-integrity test failed (should also show you a warning on login)?

I have exactly the same problem

I found this topic related to the problem:

but they haven’t seen issues since NC 11. So if it still exists, please open a new bug report on the bug tracker.

On newer setups, there is also a command to clean invalid shares (in case this is creating your problems):

 sharing
  sharing:cleanup-remote-storages     Cleanup shared storage entries that have no matching entry in the shares_external table
