FB Login doesn't work if user try to login on K2 item

As the subject,

User can't login if they're try to login from K2 item page..
Here is the example:

Standard Joomla article:
http://www.mahasiswait.com/term-of-use.html

K2 item:
http://www.mahasiswait.com/component/k2/item/51-test-page-1.html

Is there any separated plugins that make this thing happened ?

PM me if you want access to back-end

I suspect that problem is in K2 social icons, please for test disable this icons (facebook, g+ etc) in K2 articles and check whether it is working without this part.

I'm not found the way to disable it on K2 parameters. How can I do that ?

I have disable the K2 social icons, and it isn't solve my problem.

Here is the example:

nb: I use add addthis on K2 and SP Comment Plugin for the FB comment box

There are two fb-root elements in your site code so the facebook script can't work. Second one is added by comments - please try to disable them and check whether then pop-up is working if yes we can try to avoid this duplication.

You Right !

It solved if I disable the other things that connected to FB, such as comment plugin, FB Likes from add this, FB likes from K2.

I think it will be very nice if the Gavick Team fix this issue for next update, so we can use some FB connected plugin but not affect our lovely FB login plugin.

Thank you.

nb: sorry for my bad english

Yes, we surely try to resolve it is some way but it this is more facebook issue that our extension. Facebook scripts don't allow to initiate them several times - only once, but different extensions include the same script and this is causing problems.
