ISSUE SUMMARY:
When I sort Groups by 'Most Active' it returns a strange order, but not apparently related to its activity that we can tell. Are you able to check if this is working?

STEPS TO REPLICATE:
1 Log in and Go to main JomSocial page where Groups are listed (our home)
2 Sort Groups by "Most Active"
3
4
5
RESULT - Top of the list is not the most active. They also aren't in reverse active order, as far as I can tell.

Hi, Geoff.

This sorting works fine. "Most active" sorting uses "wallcount" column values and and highest value has "India, Singapore, Sri Lanka Church Areas " group = 26. It means it has most items on group activity stream.

You may check that in database, in table _community_groups. Just sort by values in "wallcount" column.
