The main page of newly created subforum just disappeared

[alehro]

Several hours ago I've created subforum 'MNP News' in this forum http://mnpforum.alehro00.com. The newly created subforum  worked for several hours.
Now it says :
Firefox can't find the file at http://mnpforum.alehro00.com/MNP-News-f4638944.html

Child topic pages are valid.

Does anybody know what's going on?

It's working for me now. Perhaps the Nabble servers or a link in the Internet chain between them and you went down for a while?

Hi Greg,
Thank you for the help. The problem was in my browser (beta version build of Firefox). It's the first time I see such kind of bug: refusing to load particular page. I don't even know how to report it.
