“Sorry, you are not allowed to access this page.”

Hello,

I installed the plug-in in order to create a schema for Woocommerce produce. However, whenever I click on one of the tabs in Settings, I get the:
“Sorry, you are not allowed to access this page.” message. I have admin rights and it doesn’t happen with any other plug-ins. I am running the latest versions of WOrdpress and Woocommerce.

Any help would be greatly appreciated.
Thanks.
