Hi!

I had the same problem with firefox and navigation that causes trouble after update of DNN 5.4. At first I thought it was a bug because it worked on most browsers I tested except firefox.

I tested whether it was the same problem with other computers that I had firefox installed. I found that it worked at all except my computer. I tried to reinstall firefox again and it solved the problem.

I hope this information saves time and others will benefit.

snap! I have exactly the same issues with the standard skin which was fine for a short while (1 day).

I have just updated FF to 3.6.3 because I too was having display problems such as menu displayed in list and menu would not render (works fine with I.E.).

I tried to get around this by installing a black-vision-orange skin which I know works fine on another site running dnn 5.1.2, this corrected the menu problem but I now have other issues on the site settings/host settings pages. When I select any radio button or drop down items the page posts back straight away so I cant make any confirmation or save setting link clicks.!!!!

I have had other problems with 5.4.2 so thought this latest issue could be related to the new DNN install but I cannot find any reference to 5.4.2.

The main Dnn.com site menu also displays as a site list and has no menu but strangely this page I am creating a reply on displays the correct menu bar?!?!?!.

I had 2 or 3 windows updates this past week could these be effecting things?

I bypassed this problem by using DDR menu.
