First: Thank you! I love Really Simple Facebook Twitter Share - it's my go-to plugin for adding sharing buttons.
Second: I've noticed in the past few days that the counter for the Pinterest button is no longer showing up. This is on multiple sites (one example: http://buenovida.com/2012/12/04/tomato-butternut-squash-soup-vegan/ at the bottom ). The posts previously had counter numbers, and they have pictures, so I know they have been pinned successfully already.
I tried un-checking the "Show Counter" option, saving, then re-checking and re-saving, but that didn't help.
