Failed import from WordPress
 

I'm trying to import from WordPress. Impex didn't work out of the box, but adding an options_everyone field to the blog_users table fixed that. There's also an issue with WP post revisions, but I purged them and spurious users from WP while I was at it. I'm getting errors when I try to view anything that outputs an index though. The script blog.php throw this error:

Fatal error: is_member_of_blog(): $bloginfo['permissions'] not defined. in [path]/includes/blog_functions_shared.php on line 281

Any help? I've been at it for hours now. :)
Thanks,
adam
