I have been playing with w3 total cache and found that it conflicts with some things. I disabled minify, object cache, and database cache, to alleviate the issues. Now I am having social sharing issues. I tried another plugin called slick social, which looks great, but has the same issue as floating social. My shares don't show up on facebook. They do on twitter and linkedin, but not facebook. The like counter increases but no article share on fb. Any thoughts on why?
