Users Loosing Navbar in vB
 

I went to vBulletin.com and got the standard answer for this issue, uninstall your mods, we can't recreate the issue, we don't know, blah, blah, blah....

Anyway here it is. I have a few users using Firefox who cannot see the upper part of my navbar ( I have two, one above the login and one below) and they can no longer see images I have for different groups in the postbit. If anyone has seen this issue or knows how to fix it I would sure appreciate it.

Thanks in advance,

Most likely it's your html/css issue - I suggest looking into your templates.
Compare them to the original vbulletin templates.

If you check the multiple menu url in my sig, it will take you through the basics of builing a navbar. This may give you some pointers when checking your templates.
