Pay with a like display is too narrow

I have installed Pay With a Like on my site at but it us unusable at the moment.
The "share" button seems to work, but doesn't unlock the hidden content.

The "Like/Recommend" button causes a comment box to drop down which is only the width of the button itself, obscuring the text and the submit (?) button (dunno what it is - I can't see it).
I accidentally got it to work once in IE, but not in any other browser. I have tried disabling the Facebook Comment popup with no luck.
I am using the Weaver ii premium them but the problem persists when I try generic themes such as 2012 and 1014.
This offer is due for launch on Monday, and PWAL is an integral part of the strategy. so I need you help ASAP.
