Working with feeds is great but things can go wrong at different levels. In this article I will try and give a heads up if I run into problems.
Facebook SDK plugin - Plugins in general
There are many plugins doing all kinds of stuff in Joomla. Most do this correctly but some 'blindly' add code to any component output. When this output happens to be KML/XML it might get corrupted with this code.
One example is the Facebook SDK plugin and the social sharing plugin from KA. See my comment in their forum.
