Hi Sam @investa
There are two pathways to creating groups – clicking on the group tab and using the “Create” button found there or hovering over your avatar in the upper right hand corner, and go to Groups>>Create a Group. Can you let us know which path you are using and if both paths seem broken on your site?
I just tried both pathways on my test site and they seem to work. The group is actually created on the first page when you click on “Create the Group” button. The subsequent dialogs serve to set up the group configurations. Did you check to see if the group has actually been created?
Sorry for all the questions – we just need a little info to go on. Thanks.
