That said if you are going to import a 6.5 dbase then you need to run the import script in the members area and follow the directions from the members area.
I would not attempt any shortcuts unless you are very friendly with ubb.

Note:
There is a bug where since version 7 a new class moderator was added and causes a issue.
By upgrading to like 7.0 then 7.5.7 will help.
Or just fix the issue after upgrading.

I used the upgrade.php file to update the forum from 7.5.6p2 to 7.5.7.

How can I see if I got the problem with the "new class moderator" and how can I fix it after upgrading ?

@Gizmo: I used this upgrade guide to upgrade my forum:
upgrade guide

Is this an old guide ?

But all my problems still exist....should I or can I run the upgrade file again when uploading all the files again ?
Perhaps the were some problems with the first upgrade...

Thanks
