Hi,
We are aware that failure. Currently there is no convenient fix for that, it is as it is.
AJAX loading breaks the social media icons. Because we are using 3rd party external sources to load those social media icons (addthis.com and official facebook like box). But i am sure there will be a patch for it soon. The solution would be, after AJAX loading is completed; the JS of Addthis and Facebook have to be reloaded.
Maybe at least using "iframe" (instead of HTML5) would solve the problem for facebook like box, but i can't say anything without trying
Regards.
