Why do I get this "access denied" message?

When I click on the go to first unread message button in this thread – http://boards.straightdope.com/sdmb/showthread.php?t=598262

I get a message that says I don’t have permission to access this page.

What’s up?

I was able to see the thread when I clicked on your link.

It was probably moved to one of the moderator-access-only subforums which you don’t have access to.

edit: me too. so scratch that idea.

I can see the thread when I click on it too. That’s not the point.

It’s when I click on the “view first unread message” button in that thread that I get the message.

Maybe this link will be more helpful – http://boards.straightdope.com/sdmb/showthread.php?p=13543247#post13543247
