[Plugin: wpLike2Get] Facebook option NOT showing up

Are you using addthis as Plugin or with custom code on your site? Can you give me the URL to your site?

I think you have a problem with another plugin. You get JavaScript errors from the “gigya”-Plugin. Deactivate this plugin and try wpLike2Get once more.

Maybe from this: http://wordpress.org/extend/plugins/gigya-socialize-for-wordpress/

I have take a look at your site again and you have the same errors like before.
