I have a customized Navbar. With the Log Off button, for some reason it is visible with Firefox but fails to appear in the navbar when the forum index page is viewed with Chrome.
Any hints on how this can be rectified would be appreciated?</font>
I cannot tell what template you edited in order to let that show up, but my guess is going to be Breadcrumbs/Navigation Templates->navbar. To be sure, enable HTML template comments in vBulletin Options and check the source to see where you did it.
