I recently downloaded your forum, and I must say it is a nice plugin. I am having an issue though with changing permissions for certain roles. When I go to change them in the forum edit page I get this error "Error updating Forum ID 7. It is likely your roles haven't been updated (WPBB -> Tools -> Refresh Roles)". So I went over to the role refresher, and I then got this error "Failed to refresh roles, please try again or make sure you have made changes to the roles". Now I have tried changing the roles in WP, and even creating new ones. I will get the error from the role refresh tool, but it will add the new role to the forum check box list. It won't let me check any of the permission boxes for that role or any of the others tho.
