Anyways, i did a bit of testing, disabled all the plugins and got a same result on the same theme, when i switched the theme to default wp theme it seems like index.js is loaded correctly and validation is working, so it’s safe bet that some part of our custom code functionality causes this error, any idea which change from 5.9.8 to 6.0 would cause this error so i can troubleshoot our code further? This is currently the way we echo form in php:

  <?php if (!is_admin() && isset($form) && $form) : ?>
  <?= do_shortcode('[contact-form-7 id="' . $form->ID . '" title="' . $form->post_title . '"]'); ?>
  <?php endif; ?>

The issue was in this piece of code defering wpcf7 js files on the load, so probably that was the reason wpcf7 was declared as undefined:

add_filter( ‘script_loader_tag’, function ($tag, $handle, $src) {
if(!is_admin()) {
$tag = ”.”\n”;
}
return $tag;
}, 10, 3 );

Hello,
could you kindly explain it better (and how you have fixed it)?

@bipolab Well i guess they changed how the validation works now, at least what i am sure off is that wpcf7 scripts are being required to be loaded immediately for initialization of wpcf7 object, so in my case i have been using that filter above that actually deferred wpcf7 js scripts and that was causing wpcf7 object to be undefined. If you are having the similar issue it’s probably because that wpcf7 js script are being deferred, i would suggest you to check the source code on the page and look for wpcf7 script being correctly inserted on the page without being deferred. In my case i just had to remove this filter from functions.php or to add a check for specific id of the scripts and exclude it from deferring.

Thank you for your replay.
