PGLS

That also gets a mention in the above valid link.

Although I'm not having the problem discussed here, I did try the link, and got the response, "Sorry, we couldn't find that! You do not have permission to view this forum."

I was able to view other forums/topics on the Perfect Parallel forums, which leads me to suspect this one is only visible to a limited number of admin/priv users.

Yes it seems as though the "Perfect Golf Bug Reporting" forum is only available to certain groups which was totally silly

http://www.perfectparallel.com/forum/11-perfect-golf/

If it's missing from the above forums list link that will be the issue.

With a bit of experimentation I figured out that the forum/topic in question is only visible to registered logged-in users. Anonymous users will get the screen described in my earlier post.

Or at least that's what happened to me.
