I'm having issues with comment plus in a subsite of my multisite.. I created a screen video (see link)
There is no audio just visual of (1) facebook issue (you'll see it) and (2) issue at the bottom with the overlapping of "comment via twitter" and check box. For issue (2), there was a previous wpmu solution but I can't find it in my backend. There was some code that I need to place in my main site code for all subsites.
