Hi there,

The validation.js script requires the jQuery validate plugin. Since you’re getting that error it’s an indication that the validate plugin is either loading too late or isn’t loading at all. Can you post a link to the page where this error is thrown so we can investigate further? There may be another WP plugin that’s removed the jQuery Validate plugin, but if we can check the page we can find out for sure whether it’s gone or just too late.

OK there’s some customization that was done. Have you discussed this issue with the developer that made the customizations? This code was added to the middle of the page somehow:

jQuery(function(){
 //Registration form validation
 jQuery('#event_espresso_checkout_form').validate();
});

The problem is it’s too early to try to run that code because the validation plugin hasn’t been loaded at that point. You could try loading that code later (use the wp_add_inline_script() function via a custom function). Or you could change the code so it runs after the document is ready:

jQuery( document ).ready(function($){
 //Registration form validation
 $('#event_espresso_checkout_form').validate();
});

I’m afraid I don’t understand your question. You’re not actually going to put in anything new, but rather change what was already added via a customization. I do not know how the customized code was added, so the first step in fixing this is your find where this code was added:

jQuery(function(){
 //Registration form validation
 jQuery('#event_espresso_checkout_form').validate();
});

And you change that code so it executes later on in the page load (on document ready).

Hi there,

I didn’t actually suggest to change the validation.js file. I made a suggestion to change the inline JavaScript.

I don’t know because I do not know which page or file your custom code was added to.

I used the Chrome browser’s View > Developer > View Source feature and looked through each of the JavaScript files called on the page.
