Hello. I just installed Joyn a few days ago and I am having the same problem. I purchased this theme because I also have Flexform which is not coded for buddypress although the issue I am having now was not an issue in Flexform. Anyway, I have set my buddypress pages. Members, Activity Streams and User Groups are working great. Register and Activate are now sending me to a php 1178 cannot modify header. This is when I click on view. When I logo out of my admin and try to login as a random user I have created it will take me to the same screen. I believe I have pretty permalinks or almost pretty. Is this something on the FTP side that needs to be modified?
