I am using URE 4.9 and it seemed fine, but after upgrading to wordpres 3.8 I had to reassign capabilities to users. Maybe it makes sense, you should always do a back up before upgrading.
But I created a custom role and I want to delete it, but I am not able to see Delete Role button anymore (I have Add Role, Add/Delete capability)
The problem is I have to delete that role, because I have done some logic with user roles and it mixes everything up.
Deleting the role from usermeta table is almost impossible because the capabilities field is so overloaded for a single user.
