I have had few reports already that if username has spaces or dots, users can not login to forums. Login is working fine when going from main site instead, so it has to be something with the forum login form settings in this theme.
Search: “Validation Form - login”
Remove the code below or modify to suite your case.
( if you remove remeber the “,” at the begin of code.)
message: 'The Username can only consist of alphabetical, number and underscore'
Ok, thanks for this one. I can shout out that it should be fixed now!
