Featured Image Size

With the new Wordpress update, my plugin to resize feature images containing the code

function modify_featured_image_size(){
    add_image_size( 'activello-featured', 1080, 1350, true );
}
add_action( 'init', 'modify_featured_image_size', 10 );

is no longer working. I’ve tried regenerating thumbnails and everything.

Thank you.

Hey there,
Hope you’re doing well today

What’s the name of that plugin?
Maybe you could try finding another plugin that works. Possibly Code Snippets (see link below).

Another option would perhaps be to manually add the code to functions.php.
