NextCloud 17 on PostgreSQL (nginx + php-fpm) - cannot create groups or users after fresh install


I just did a fresh install of NC17 on CentOS 7 and PostgreSQL but for some reason I cannot add any groups or users!

I cannot see any errors in the logs although I get a pop-up saying there was an an error with the request.

I also cannot change the language in the settings -it will revert back as soon as I refresh the page.

I know it’s not SELinux because I’ve disabled it with: setenforce 0

Nothing in Nginx logs either…? It just silently fails…

Anyone got NC17 running nicely on PostgreSQL?

I would appreciate any help troubleshooting this very much!
