You have other Facebook integration extensions installed on your site. They are also including the Facebook Javascript file connect.facebook.net/es_ES/all.js. You'll need to disable these extensions or set them not to include the Facebook library, if that's an option:
itp-fblike-box
K2
You can use the Autotune configuration tool, in JFBConnect, as well. That will alert you if other extensions are including the Facebook Javascript file.
Hope that helps,
Alex
