Error Notice On Products

Hello,

I am receiving the following error message on our product pages. We have deactivated plugins apart from the WooCommerce one. When WC Vendors is deactivated the problem goes but I need WC Vendors for the site! We have also swapped to the storefront theme and the issue is still present.

Notice: user_id was called incorrectly. Order properties should not be accessed directly.
