there is something broken with the roles & shop_manager role of woocommerce.
when I use the role even with all rights from user role editor pro enabled, the search for e.g. orders will redirect me to some random backend page instead of showing search results.
when restricting the rights to only include rights that are needed for the shop manager it will redirect to the Comments page instead of showing search results.
for other users e.g. Editors when using the search everything works perfectly fine (e.g. search for products) or the admin (even when searching orders) it works perfectly fine.
Do you use “admin menu access” add-on and restrict some menu items for this role?
If ‘Yes’, send me full URL with parameters which was redirected to other menu items after you click search orders button.
