They sent details. Plugin installed.But can’t go plugin settings page.
Show “Sorry, you are not allowed to access this page.”
My plugin is https://wordpress.org/plugins/bizpay-internet-payment-gateway-bizpay-ipg/

Not only that but also I can’t go to
Order Manager > Payment Gateways >Note: More payment gateways can be found on the theme plugins page here too
