I cant see a page after logging in

If I visit this page (http://www.jalopyjournal.com/forum/...lock-engine-manual-and-other-goodies.1005974/) before I login, I can see the content. If I login, I get the the following message:
The H.A.M.B. - Error
You do not have permission to view this page or perform this action.

Is there an issue?

 

I get the same results when logged in to the site using Firefox. Have you tried a different browser?

I think there's also a chance that the page may have been deleted or moved to a different forum page on the HAMB. What you're seeing when you're not logged in to the site may be a cached copy of the page stored on your computer. If you clear your browser's cache you may not be able to see the page whether you're logged in or not.
