BuddyPress.org

Hi everyone..

So suddenly the groups wizard fails at step 2:
1.) Enter group name etc
2.) next step is blank – you can only see the buttons “continue” or “go back”. As mentioned before, there is no options shown in this step. It’s just blank.
3. ) Clicking “continue” —> Are you sure you want to do this?

Setup:

WordPress Multisite 4.8.1
BuddyPress 2.9.1
No caching currently running in front of the server (like Varnish or cloudflare)
PHP 7.0 
We are not at bluehost. 
Conflict testing done= no conflict (e.g. disabled all plugins except for BuddyPress)
Also tested with WP standard theme = no change. 
VPS server with 6 cores / 32 GB memory

Reinstalling is not an option, as we been working for a long time on the systmem, (WordPress MU).

I been googling this for hours and hours, it seems that many before me has had this issue, but so far I haven’t found a described solution to this issue.

So any help or advise in the right direction to solving this issue would be very appreciated.

Kind regards
