After buying the Pro version and giving it a good review, I'm disappointed to note that the plugin is not reliable.
First, it worked on my site even while I was logged in. In other words, I could like/dislike posts & comments while being logged in. Then it stopped working while logged in, but it worked when not logged in. That was fine with me. It worked in IE, Firefox and Chrome.
Now it stopped working in Chrome, when I am not logged in. All I see is
below a post. No image, and no link.
I will see if having gone "Pro" will garner more support than the free version gets.
At this point, I am not happy.
