If you don't have any other products at the top of showthread I'll have you do a simple diagnostic. Paste the following in at the bottom of the Threadnav Search plugin:

PHP Code:

$diagnose = 1;
if($vbulletin->userinfo['username'] == 'osix' AND $diagnose == 1)
{
        die($numthreads . ' threads found');
} 


Change "osix" to your forum username. Refresh showthread and you should get a white page with the number of threads found in the search. If you have just clicked "Mark Forums Read" you won't get any results until someone posts a new thread. You may want to go to your user settings and click on ThreadNav Control and switch to "Today's Posts". You can disable the code I just posted by editing $diagnose to a value of 0
