error on activation

When I activated your plugin just now, I got an error message: “Sorry, you are not allowed to access this page.” on a page with the URL https://mydomain.com/wp-admin/admin.php?page=olympus-google-fonts

Returning to the dashbord, I was then able to use your “Settings” (Customize) screen, but getting an error first thing on activation certainly puts me on guard for more problems!
