Deactivate all plugins except BuddyPress and change to bp-default theme, clear cache and see if you can now create a group. I assume you did not disable Groups in BuddyPress > Components. https://codex.buddypress.org/getting-started/configure-buddypress-components/
Btw, what do you mean by “There is no such thing like “Create a group” in the backend.”? You create a group in front end of site.
Ok, I thought it could also be done in the backend. The groups function is enabled. Just have activated the default theme and here it works. I am developing my own theme so i don’t want to shred this. Maybe some code is missing… All Buddypress templates are implemented thus the error MUST be in my theme’s templates. It’s not the functions.php, already have checked it.
Doesn’t anyone have an idea?
What theme are you using?
I’m using Saffron and having the same problems
@number_6 you might need to update template tags in Saffron theme’s header.php which you can double check by comparing with header.php of bp-default theme https://trac.buddypress.org/browser/tags/1.2.8/bp-themes/bp-default/header.php
