Hello there,
I hope you’re doing well :D.
Seems the dashicon font is not loaded on your site and for this reason you see the box.
Maybe another plugin or your theme remove the section.
Try with the following code in the functions.php and see if the problem is fixed
if ( ! function_exists('yith_dashicons_front_end') ) {
function yith_dashicons_front_end() {
if ( ! wp_style_is( 'dashicons', 'registered' ) ){
wp_register_style( 'dashicons', 'https://schwepper.com/wp-includes/css/dashicons.min.css?ver=5.9.3' );
}
wp_enqueue_style( 'dashicons' );
}
add_action( 'wp_enqueue_scripts', 'yith_dashicons_front_end',999 );
}
Please, try it and let me know.
Have a good day.
