MY TEST FRONT END GROUP CATEGORY PAGE:
https://www.mysite.com/test
Couple of significant problems on the GROUP CATEGORY LAYOUT (link provided)...
1) When not logged in, the usual "Login to view more stream items" doesn't show - inconsistent with all other areas where the stream shows up, and it means the guest user might assume all that shows is all there is.
2) When a user does log in (I've provided a real user account for my site in the additional info box) and clicks 'load previous stream items' then all that loads are the stream items relating to that user.. nothing to do with the group category!!!!
