I upgraded to the newest version of the plugin and it looks like the button moved down, on both Firefox and Safari. On all the posts and front page of the site, it now overlaps with the button that was first sitting neatly below it. No other plugins were upgraded, and I can't figure out what else could have caused this change.
Did something change in this update that could have moved the location of the button down by a few pixels? And how can I fix it? (I'm considering deleting the plugin and reinstalling the older version to see if that fixes it, but want to wait until the weekend when we don't have as many site visitors.)
