WP 4.5 and contact form

Dear Kriesi,

Another problem that seems to relate to the WP 4.5 update is that the contact form on my website has stopped sending messages.

I added the temporary fix to the functions.php to fix the slider issues as I cannot update Enfold at the moment. Perhaps this has an impact?

function modify_jquery() {
if (!is_admin()) {
wp_deregister_script(‘jquery’);
wp_register_script(‘jquery’, ‘https://code.jquery.com/jquery-1.11.3.min.js’);
wp_enqueue_script(‘jquery’);
}
}
add_action(‘init’, ‘modify_jquery’);

Has anyone else encountered this issue?

Thanks, Richard
