Content Plugin not aligning properly

Giovanni,
I'd recommend trying to increase the width of the Like button (a setting in the Content Plugin configuration area) or setting it to not show faces. When the Like button is on top of an article, the faces will show below, and depending on your template, it may not expand properly.

Hope that helps get you going, but there's only so much we can do about those buttons as they are loaded from Facebook itself. The other option is to change it from the standard count to something else which has a more fixed width and height (like box or button count).

Good luck,
Alex
