I apologize for writing here, but I am having trouble posting it on the new forum...
I had jetpack installed (latest and current version) and tried to put the FB box on the Home Widget 3. The space shows up, but it is empty, only the title shows. As it did not work, I deleted Jetpack from the plugins and installed the facebook plugin, but much to my disappointment, the problem is exactly the same...so I thought...hum...could it be the compatibility with the responsive theme? That's why I am asking you. Here is my website, http://www.medjugorje.pt, I am leaving the facebook follow button on the Home widget 3 so you can check it out.
