jquery - validator $.validator.methods[method] is undefined

I have this validator form code I have inherited which I am getting this error:

$.validator.methods[method] is undefined 

and under that it's showing

'maxlength:$.validator.format("Please enter no more than {0} characters.")'

I have read that it could be spelling mistake or method being called that's not there. But can't see it.. even read about remote data element could be causing issue but taken it out it breaks.

edit: I have uploaded none compressed js code and error points to this line

var result = $.validator.methods[method].call( this, element.value.replace(/
/g, ""), element, rule.parameters );

code:

$(document).ready(function(){
    $("#regForm").validate({
        rules:{
            confirmemailaddress: {
                equalTo: "#emailaddress"

You are getting this error because you're calling a non-existent rule...

rules: {
    //other rules,
    interest2: {
        notEqualTo: "#interest"
    },
}

notEqualTo is not a valid rule included within this plugin. You must remove it or create a new rule called notEqualTo by using the plugin's built-in addMethod() method. Something like this...

jQuery.validator.addMethod('notEqualTo', function(value, element, param) {
    return value != jQuery(param).val();
}, 'Must not be equal to {0}.' );
