Hi Con,

Thanks for your reply. I’m aware that the default is date, but it simply wasn’t. I also have no clue what plugin could’ve caused it, since I use all the plugins in multiple websites.

In the end, your stackoverflow link helped a lot!
I changed the code to this (which works):

if( is_admin() && $_GET['post_type'] === 'shop_order' ){
	if(!isset($_GET['orderby'])) $_GET['orderby'] = 'date';
	if(!isset($_GET['order'])) $_GET['order'] = 'desc';
}

Thanks and have a nice day!
