Nextcloud version (eg, 20.0.5): 20.0.8
Operating system and version (eg, Ubuntu 20.04): Ubuntu 16.04
Apache or nginx version (eg, Apache 2.4.25): 2.4.18
PHP version (eg, 7.4): 7.4.15
The issue you are facing:
I updated to Nextcloud 20.0.8 using the built in updater and stable channel. I can no longer log in. As soon as I enter my password and hit login, I get an internal server error.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Sadly, I don’t have steps to reproduce it.
