I installed that one too and got the same issue. I still don’t see the comment box in Firefox, but if you see it in Firefox, that only tells me that there’s something wrong with my Firefox. If other people can see it, I’ll just take that for now.
Okay…..
I deleted this plugin and installed the official Facebook plugin. Initially, that plugin didn’t show the comment box either. But, I realized that I’m using the latest version of Firefox. So I viewed my site in Internet Explorer and in Safari and in both browsers, the Facebook comment box showed up. I’m gonna take a shot in the dark and guess that Firefox is the problem. No matter how many Facebook comment/like plugins I installed over these past few days, none of them would show up when I viewed them in Firefox. Any reason for that occurring?
I switched my domain. Here’s a new link to show you the problem.
