Problem with icons

Hey guys,

I have install this plugin in 3 different wordpress site… The two of them working just fine.. In the last installation I icons are not appear in the website only number of counts and name (etc “post”) I have check the html code and I can see that icon is not included either in the code, I have also double-check the design in the options of the plugin and it is select a design with icons !

A weird problem is that Icons appears just fine in the footer of the page but not in sidebar :-/

Any ideas what cause this problem ?
Thank you
