I actually read that post right before installing. I used the update lsql_Links set link_claimable="1" where LinkOwner = "Admin"; to set all the admin owner links to claimable.

The problem is the error occurs even before you try to claim the link. When I send the e-mail to invite someone to claim a link they click on the url and then login. Right after login they get the error message.

I don't even have the plugin installed now but my modify.cgi page is now throwing the error. I have no idea what is going on.
