Upgrade from 4.8c to 4.8.1 problem
 

Upgrade gives this error on gallery page:-

MySQL error reported!

Script: index

Query: SELECT groupid,cpaccess,modaccess,diskspace,uploadsize,uploads,comments,editpho,editposts,useralbums,reqmod,canassign FROM usergroups WHERE groupid='6' LIMIT 1

Result: Unknown column 'canassign' in 'field list'

Database handle: Resource id #7

Your missing the field from the upgrade47.php run that upgrade file

Done, thanks.
