How to Remove URL Field From WordPress Comment Form

1. Add this code to your child theme’s  functions.php file or via a plugin that allows custom functions to be added, such as the Code snippets plugin. Avoid adding custom code directly to your parent theme’s functions.php file, as this will be wiped entirely when you update the theme.

add_filter('comment_form_default_fields', 'custom_website_remove');
function custom_website_remove( $fields ){

	if( ! empty( $fields['url'] ) ){
		unset( $fields['url'] );

	return $fields;

2. Add the following custom CSS code in Theme Options > Styling > Custom CSS > Custom CSS:

#respond .comment-form-email {
	width: 100% !important;
	float: none !important;

3. Make sure to clear both, your browser's and website's cache after saving Theme Options and before viewing changes to your website.
