You should compare your navbar to the default one (go to edit it and hit View History > Compare) or just view the default one and manually look at stuff. If you did, you'd see this in your template:

<if condition="$show['quicksearch']"><script type="text/javascript"> vbmenu_register("navbar_search"); </script></if></td>
		</if>

And this in the default one:

				<td class="vbmenu_control"><a id="navbar_search" href="search.php$session[sessionurl_q]" accesskey="4" rel="nofollow">$vbphrase[search]</a> <if condition="$show['quicksearch']"><script type="text/javascript"> vbmenu_register("navbar_search"); </script></if></td>

So also have some 'blank' if statements... why? Maybe you should redo the navbar template step-by-step and make sure you aren't breaking anything after each addition.
