 * tammbo,
 * I suspect there is a bug with your version of WordPress. I have added this to
   our bugs list and it should hopefully be corrected with the next plugin version.

 * I looked into this further and as of the current plugin version (1.0.2), the 
   plugin needs a WordPress version of at least 3.3. Hopefully in future plugin 
   versions we can expand the backward compatibility.
