JQueries Crashed Problem I guess on Magento

Uncaught ReferenceError: FB is not defined                                                  (index):154
(anonymous function)                                                                                    (index):154
o                                                                                                             jquery-1.7.2.min.js:2
p.fireWith                                                                                               jquery-1.7.2.min.js:2
e.extend.ready                                                                                       jquery-1.7.2.min.js:2

What does it meant when I see that error on console?

How can I fix?

I have a custom theme, after I install a facebook like coupon extension (a popup box with coupon code will be appeared and generated when I click facebook LIKE button on product page). However, the facebook module work but some of my customed theme block gone or contents does not load. I tried to rename the js folder which put in folder skin/frontend/customtheme/js on server, the theme back to work but the facebook popup box with coupon code doesnt appear.

How can I fix? Thanks for your help.....

I have added javascript and jquery as topics.

To start with you might want to download the latest version of jquery (1.10.2) as you are using 1.7.2 and that is an older version.

Then you might want to check the error console when you load the page to see if something is failing to load and that results in undefined elements.

The uncaught exception does not tell us anything ecept that you have a fatal error.  Without a link to the page there is no way for us to know what is wrong with the code.

Thank you http://www.i-senses.com/for-her-6.html here you are the link.
28 CSS files, 22 js files, including the old 1.7.2 version of jquery loaded twice from 2 different sources.  Error console full of warnings and at least one hard error, and the page does not validate, including an error about undefined FB properties.

The page is a disaster.  It need drastic cleanup, trimming and rationalization.  There is no valid page on Earth that must have 28 CSS files and 22 js files to run.

I would not even begin to know how to run corrective diagnostics until the code is cleaned up.
