0002508: Unable to Add User to list which is already on another list.
On the list Membership page I enter the email address of a user I wish to add. As the email is already on another list, it shows up below with a link labelled "Add" and the text says click Add to add it to the list.
The link is to: /?page=members&add=1&id=1&doadd=11
I click the link and nothing happens... The user isnt added and I'm back to square one. No errors in the php log either...
