Project Description:
I have a live buddypress site and basically just found out that although as an admin I can add friends, post status updates, join groups, use pagination (all of these are ajax calls), users however can not do this, nor can people who are not logged in (using ajax pagination).

I've tried a myriad of ways to fix this, but even updating my functions.php file to a buddypress theme that I purchased, doesn't seem to do anything.

Help with this is greatly appreciated.

Skills required:
AJAX, PHP, Wordpress
