He seems to be using .html extentions for his navbar links.

So Polo, you need to add every link in your massive drop downs into the settings boxes there.
For instance, your first "Forum" drop down link is to Official Forums and the link is forum1.html so you will have to add forum1.html to that list in the settings. Second is forum104.html, so you need to add that file too, etc. You will need to add an entry for each link....and you my friend have a ton of them.
