[Plugin: Auto ThickBox Plus] not working

Hello,

I’ve installed Auto Thickbox plus and I’m using the latest version of Thematic. I’ve deactivated all my plugins except this one and the following are not occuring:

This does not show up in the footer:
<script type=’text/javascript’ src=’http://example.com/wp-content/plugins/auto-thickbox-plus/thickbox.min.js?ver=1.x’></script&gt;

The class=”thickbox” attribute is not being added.

I also tried checking the original thickbox option and it still doesn’t work.
