Hi Vladimir,

Thanks for your reply.

1) What do I do with woocommerce_duplicate_product_capability? Do I add this using ‘Add Capability’ and then keep it unticked to disable duplicate product?

2) Unfortunately I do not see the Revolution Slider Meta Box option either? But the Author Meta Box is created by the 3rd part plugin WC Vendors – specifically WC Vendors Pro. I have emailed you a copy of the plugin. Unfortunately it does require activation and I only have one license. So I can provide you access if you need to my site? If you need any help from the developer of the plugin they are very helpful and there forum can be accessed: https://www.wcvendors.com/help/forum/wc-vendors-pro-support/

3) I have done this and it has not fixed it. The role which this notification appears on is actually created by the WC Vendors plugin, the role ‘Vendor’.

Many Thanks,
