When attemting to save a forum thread page on my computer, instead of the topic and page automatically being inserted for a file name I get "forum display" for a file name and it is not a HTML file that is being saved. This does not happen in all of the forums, only a few. What is wrong?

Since we rely on the moderators backing up their forums by saving the current topics, we need to know what is wrong with the UBB and how to fix it.

Thanks for a response.
