I don’t want usernames with caps. I want the ERROR from Restrict Usernames to be parsed correctly on BuddyPress so instead of seeing ‘Only lowercase letters and numbers allowed.’ you see ‘Your username is not permitted.’ or something similar WHEN and ONLY when the username is listed on Restrict Usernames 🙂
I’ve just released v3.1 of Restrict Usernames. It fixes compatibility with the latest WordPress (currently 3.2.1) and also specifically adds compatibility with BuddyPress (v1.2+ and v1.3). Definitely a recommended update for everyone.
This means everything should work as expected. You won’t see ‘Only lowercase letters and numbers allowed.’ if the error is really due to Restrict Usernames. Partial matching should work as well.
