@tenoch. Thanks. From looking at your site, the problem is definitely that jQuery isn’t loaded. You can prove this for yourself by viewing the Error Console for your browser. If you use Firefox, you can access it via Firebug. If you use Safari, you can access it via Develop > Show Error Console. If you check you will see the error: “EFLPRO Critical: jQuery is not loaded!”
There is also some javascript error that is unrelated to my plugin. The exact message is “ReferenceError: Can’t find variable: hs”
So, you need to load jQuery in the plugins manager, and then we can check it again from there.
