After filling out all required fields and entering captcha code, site just goes back to main field with "all required info must be filled in" (shows red under avatar). I don't require avatar for registration though. Other times after entering captcha code, just goes back to "enter captcha code" which is entered again correctly, then "join." Goes back to captcha field again, until antibruteforce plugin blocks ip of user attempting to register  via mobile. Anyone else have this issue? Any help appreciated.
