Re: When logged in to BuddyPress.org some links do not work?
It is actually an issue with the way WordPress, or more precisely, Automattic has created the registration script. The script allows for spaces but then it can cause login problems.
Unfortunately, that issue needs to be addressed at a different level than BuddyPress. Since all of the moderators donate our time on these boards (i.e. we do not work for Automattic), we have no control over this issue.
As I said, I had the exact same issue and the only solution I had was to create a new username.
