I'm trying to send a form on my wordpress website using ajax, but its an error 500

Question

The form is created using Contact Form 7, but the submit action is made with AJAX and a file php which made a database conection, the error return: 500 (Internal Server Error) on php file and: Uncaught TypeError: $(...).AjaxDebug is not a function on AJAX function.

In the debug file generated by WP there is nothing related with this error.

someone can help me to understand this problem?

I disabled the plugins one by one, hoping for the problem is a conflict, but nothing change.
