That is definitely a strange problem
I'm assuming this is on your n......asia domain, but if not, let me know. On that site, if you open the HTML and search for "all.js", you'll see the following line:
js.src="http://n......asia/connect.facebook.net/ps_AF/all.js";
That line should look like:
js.src="//connect.facebook.net/ps_AF/all.js";
Something on your site is converting the schemeless (no http:) link to one that includes http:// and your domain name. That could be an optimization plugin, CDN plugin, or something else. That code that is being changed is the Facebook Javascript library, which is important for a lot of functionality. My guess is that your other extension is loading that library and not being altered for some reason, while ours is.
If you can fix that, everything should work fine. I hope that helps you understand or narrow things down, but if not, let us know.
Thanks,
Alex
