Tested this bug on Safari and Google Chrome (both from my handy macbook). Using all three buttons (google+, fb, twitter – in that order)
Facebook is showing up on my posts, however when I click on the Like button…
1. The comments box pops up for me to type
2. It disappears after a few seconds
3. The twitter button gets knocked down to the next line
Google +1 button worked like a charm!
