    Hi,
    I’ve tried to use the forum converter and it does import the board, but it isn’t importing users. Is there something special I need to to to get the user account migrated over?

    It’s giving me this error

    WordPress database error: [Unknown column 'users.msn' in 'field list']

    Thanks for the help.

    Here is the fix I worked out to get the importer to work properly.

    The problem I was having was the user accounts were not being imported due to some outdated usermeta fields in the database. I simply removed the sql code from the current importer script, re-ran, and it worked correctly.

    I wanted to share the code of that mybb import script. The file name is Mybb.php.

    Hope this helps someone else who is switching over from MyBB to WordPress.

    Thanks for sharing. I am going to bookmark this right now if any other users want to import from mybb and also I am going to see notify Stephen/create a ticket for the fix.

    Hi @robkk,

    Not a problem. It didn’t seem to convert the passwords; however. Hopefully there will be an update that will convert the passwords in the future.

    Importing with the newest bbpress importer doesn’t work. The users from myBB don’t get imported. Using your MyBB.php class also didn’t help. Where can i find the bugtracker for the importer?

    Hi,
    What is ‘newest bbPress’ for you ? 2.5.8 or the 2.6-alpha version ?
    Pascal.

    This worked fine for me, changed Mybb php file as he suggested and all my users are back on bbpress
