For those of you with display issues: I'm wondering if it might be a browsing cache issue, such that your computer is pulling the "default" version of the page from a stored (cached) version, and not calling the current page immediately. I remember this happened to me when I was first setting the forum up- even when it was running, going to the page from a bookmark/link would show the pre-forum "there's nothing on this server" page until I refreshed, then it would show the forums.
If someone's willing to try clearing their browser cache, that would be great. And specifically, you'd want to clear cache but not cookies, as the stored login is with the cookies- clearing them both would mean you'd need to log in again.
