@steve – Thanks for the response!

Yes I am removing the default editor with the following code

function my_remove_post_type_support()
{
remove_post_type_support(‘page’, ‘editor’);
}
add_action(‘init’, ‘my_remove_post_type_support’, 10);

I basically need to add custom css to the content in the WYSIWYG editor, and I’m not sure why add_editor_style is not working with the Piklist editor.
