In short yes, this is my first buddypress setup so first thing I did was to test out registration
This was both in the custom-community theme and the default theme. No other plugins, except bbpress which I disabled to test, still no go.
I am on a timeline so I have reverted to 1.5.0 and the activation step worked in one go. Unfortunately I am having problems as site-wide forums arent available in that version but that would be another topic. If none of the other posters sites are still available for testing, Id be glad to set up a vanilla wp, and buddypress install and provide you with the login and password…
Something in the code has definitely changed. I guess I could do a diff between 1.5.0 and 1.5.4… If someone finds the answer before I get the chance to do that, even better, let us know.
So are you guys going to address this issue? I have the same problem on a clean install of wordpress and buddypress with no additional plugins active and have tried several themes. My site is http://www.websitesthatkickass,com/patrick/
