I am also getting the error “Your changes were not saved due to an error (or you made none!).” I have max_input vars set at 10000
I don’t know if it’s this plugin or the theme. But to make the company name required I had to: Cotomizer => WooCommerce => Checkout
Let me answer your questions one by one.
>>I have set both the billing and shipping company name fields (billing_company & shipping_company) to required but they are being required on checkout.
Please ensure that you have enabled the option “Enable required validation override for address fields.” in the plugin’s Advanced Settings tab.
