We've been informed of a bug in our version of phpBB that causes activation links in messages emailed to members after certain password resets or profile changes not to work.
The problem is caused by a security feature we've enabled to require initial account activation by administrators. Because the code is shared with the reset code, ordinary users may experience problems with not being able to reactivate their accounts after such changes.
The phpBB developers apparently have a fix for this, although it has some dependencies with other very recent patches. We'll check into what patches need to be applied and try to resolve this ASAP, however, in the interim, if you experience this problem, please e-mail Mark and cc:
