Issue: Navigation help

Run the upgrade script.

As you are seeing multiple tabs highlighted, are you by any chance using a third-party tabs manager add-on, in addition to the vBulletin Navigation Manager?

If this is the case you will need to configure the add-on to ignore wiki files. If there is an option to ignore by SCRIPT_NAME do that, otherwise THIS_SCRIPT is a little funky:
vw_wiki_index.php
vw_wiki_inlinemod.php
vw_wiki_subscribe.php
and so on

I figured out whats happening. When I change the "Asthetics" menu to set the navigation to be first, it makes two of them.

When I change it back to "standard position" it doesn't do that.

You are not supposed to be able to use that setting in vBulletin >4.2. vBulletin 4.2 has its own system to determine tab positioning. Please use that instead.

Updated to "Fixed" in the next release. In the next release, the Aesthetics setting will not have any effect, as expected.

Thank you for your help. It was a bit confusing. I knew I was doing something wrong
