I back to the AO Git and found out the fiter “autoptimize_filter_css_replacetag” in the autoptimizeStyles.php. Just overrode it (functions.php the file), worked fine. 😉
I removed the plugin and added the like button and comment box by mylsef. It was really easy.. you can get the code from https://developers.facebook.com/docs/plugins/
I’ve also implemented the facebook comments count, everything you need is on facebook developers doc.
