Ran into problems with admin bar and some themes. With my luck today, I chose most of them that don't work and only a few that does. Is there something specific that the admin bar is looking for in a theme to either turn on or off? I hope that make sense as I have no idea what to do next.

Here are the list of themes that didn't display the admin bar for both IE7 and Firefox:

http://themes.wordpress.net/testrun/?wptheme=1757
http://themes.wordpress.net/testrun/?wptheme=1759
http://themes.wordpress.net/testrun/?wptheme=1629
http://themes.wordpress.net/testrun/?wptheme=1730
http://themes.wordpress.net/testrun/?wptheme=1702
http://themes.wordpress.net/testrun/?wptheme=1728

now come on, do a search. there is a lot of posts about it. I remember personally explaining to someone, not that long ago where to manually insert the call for the admin bar into a theme if it does not get called automatically, though I can't remember it right now thats why I tell you to search otherwise I would have just written it here...

Sorry, I did search using the same terms as my subject and came up with many tags in the listing and only two pages. I finally decided to just click on your name, which did point me to a solution.

For those who have the same problem and found this post, here's the solution.

open footer.php and add to the end:
<?php do_action('wp_footer'); ?>
