I don't know that this deserves a "ticket" but was advised to post here. Here is my post to the forum:

About half the time I come over I get:

Invalid URL
The requested URL "/community/viewforum.php?from=submenu&f=46", is invalid.

Reference #9.56de54b8.1303874278.601d93

when trying to open the page, or any other under the phpbb.com domain. After some time passes I get in. I thought it was a firefox issue but when I try it in exploder, it comes up as page not found.
