Contact form 7 not working in IE

The contact form is showing an error while submitting the form in Internet Explorer.

What does the error say?

It redirects to same page and appends /contact/#wpcf7-f83-o1 to the end.
The error says There was an error trying to send your message. Please try again later..

See FAQ > After submitting the form, I get an error message stating “There was an error trying to send your message.” What is wrong?

Thanks for the information.

They removed IE support however it’s possible to get it to work again on IE 11.

Add this to your themes functions.php to get the wp-admin back end to work again:

function load_ie_11_trident_scripts(){ 
	wp_deregister_script('jquery');
	wp_enqueue_script('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js');
    wp_enqueue_script('wp-polyfill-dom-rect'); 
	wp_enqueue_script('wp-polyfill-element-closest'); 
	wp_enqueue_script('wp-polyfill-fetch'); 
	wp_enqueue_script('wp-polyfill-formdata'); 
	wp_enqueue_script('wp-polyfill-node-contains'); 
	wp_enqueue_script('wp-polyfill-object-fit'); 
	wp_enqueue_script('wp-polyfill-url'); 
	wp_enqueue_script('regenerator-runtime');
}
 	add_action( 'admin_enqueue_scripts', 'load_ie_11_trident_scripts');

Add this to your themes functions.php to get the front-end to work again:

function load_ie_11_trident_scripts_frontend(){ 
	wp_deregister_script('jquery');
	wp_enqueue_script('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js');
    wp_enqueue_script('wp-polyfill-dom-rect'); 
	wp_enqueue_script('wp-polyfill-element-closest'); 
	wp_enqueue_script('wp-polyfill-fetch'); 
	wp_enqueue_script('wp-polyfill-formdata'); 
	wp_enqueue_script('wp-polyfill-node-contains'); 
	wp_enqueue_script('wp-polyfill-object-fit'); 
	wp_enqueue_script('wp-polyfill-url'); 
	wp_enqueue_script('regenerator-runtime');
}
 	add_action( 'wp_enqueue_scripts', 'load_ie_11_trident_scripts_frontend');
