Hello together
We have exactly the same issue on our site. so i checked the plugins which we have in use together. We also use WPBakery Page Builder (and of course contact form 7 with recaptcha integration), so i deactived this one for a test. (WPBakery) Then the problem will no longer occur.
Sadly not a workarround or a fix, because this one is used to build the whole page.
May you can keep me updated and hope this one will help you!
Dear Huge-IT Support,
Thanks for the fast reply. You gave me a good hint with the console.
So I could solve the problem by my own.
I forgot to add this code in my footer:
<?php wp_footer(); ?>
Wasn’t necessary until the update to 4.0.1.
Thanks!
