MyBB Community Forums

Hello,
I converted my vBulletin 3.8.7 Forum to MyBB 1.6.1 yesterday. All is ok, but the users cannot login.
The plugin is activated, the file is in the correct folder.

Can you help me?

A temporary work-around is to have them request new passwords from MyBB. This is annoying, but will get you rolling.

I'm not sure why the vB 3 password authentications fail, please report it on the bug tracker
