Why most popular widget doesn't display on my blog ?

Hello,

First, thanks for this lovely widget :)

I've got a problem : the plugin works fine but not the widget Most Popular. On Internet Explorer it's blank and in Mozilla Firefox some code appears. I made a test (3 votes on my last post : "Prendre le temps") but nothing happened.

You can see it on my blog (using Wordpress) http://laboitealivres.free.fr at "Vos livres préférés" on right sidebar.

Thanks for helping me :)
