Hi
I found this topic
www.jomsocial.com/forum/groups/14432-joi...reshing-page-2#72599
As I too have the same issue but cannot reply/post to topic

David says - Can you upgrade your jomsocial into 3.1.1 please :)
I am running Jomsocial Version: 3.1.0.4 - and admin area - Update, check for latest version states that this is the current version - Can you please let me know which is the latest version and should 3.1.1 fix this problem
Would like to know if it does or I will implement fix in that thread.

Hi norfolkandway,

i suggest to upgrade because we hope it will fix the problem... this is not a bug so i can't say on 3.1.1 will fix the problem.. :) but we have been tested 3.1.1 so maybe it will refresh your jomsocial code..

Warm Regards,

David
