Hi @shelob9
Thank you for your linking into the discussion.
I can confirm that since excluding ‘plugins/caldera-forms/clients/render/build/index.min.js’ in Autoptimize the popup with form appears and form submission works.
I’ve followed your link and added the wp_enqueue_script('wp-embed-calderaform', includes_url('js/wp-embed.js'), array());
in my child theme but the JS error persists.
Any other ideas?
