Redirect broken after update


I updated my server from 5.0 to the current version 6. Unfortunatly, something broke during the update and I’m in need of some help. The issue is as follows:

If I open, I will be redirected to (instead of the correct …/seafile/accounts/login?next=/seafile/).

Also, the file upload broke and I’m unable to log into the client.

I would be incredibly glad for some help. Thank you!

All the best,
