I have found a glitch to do with the thread "*Mozilla Firefox*" in the Video Games section. On the index page of the video games forum, the Mozilla Firefox thread shows up normal as a stickied thread. It doesn't say it is locked in fact the last person who posted posted 8 hours ago.
However, when you click on the thread (thread title or last post button), this happens...
Notice how it says the thread is locked. It also doesn't say what the thread title is, or show what forum the thread it is in.
When you scroll all the way to the bottom of the page, there is no reply box to post a reply on the thread. As well, when you click to go to a different page on the thread, it comes up with the "Ooops, we can't find that page!" message.
