I know this seems to be a general issue, but I couldn't find a clear solution.

I have a Wordpress with a Custom page which is a contact form using jQuery.

The jQuery libraries are properly included it seems since the code acts properly, but when the form is submit, notice what appears in the console before the page reloads:

It is supposed to NOT proceed to the POST(return false;) and execute a jQuery post using the jQuery plugin serailizeJSON.

See source code and look for "serializeJSON", it will be clearer.

I would like to know why the form object does not detect the method serializeJSON?

Here is the link to test it:  http://test.rhsolutions.ca/vincent-poirier.com/?page_id=49

PS: In a page where there is only the contact form, the code works perfectly.

Thank you very much!
