[Theme iFeature] problem with css using twitter widget

Hi

Im using Ifeature theme, and for my surprise when I installed twitter widget from twitter it appears with a problem with css. Appears the icon of user with a white space between icon and text.

The script used can be checked in:

https://twitter.com/about/resources/widgets

And my web is

you can view widget in the right. I don’t know how to repair it and it’s very annoying.

Thanks
