The group stream on our website with this plugin suddenly stopped working. It took about 2 hours to find the culprit, but support rep mridul did not give up! And all that for the free version.
We got it working again as well! Turns out the 'Automatically add paragraphs' checkbox was the culprit. You should use a text box widget and leave the paragraph thingy unchecked.
I'm really grateful, we're a voluntary, non-profit sustainability group on Facebook with no budget at all. People give their (un)used stuff away to complete strangers within this group, no strings attached. We've almost reached 9000 members, so a website with a nice group stream is a very useful asset for us.
Thank you so much for your great support!
