The reason behind the error “Missing Publisher URL and Publisher Name” is because you have not setup Default Structured Data Logo and you dont have a site title on your website.
There are two things to do which will resolve this issue
1. To add a Site Title, simply log into your WordPress dashboard and navigate to Settings > General -> In this “Site Title” option you need to enter Site Title and then click on the “Save Changes” Button.
2. To resolve this issue Go to WordPress Dashboard -> AMP option panel -> Settings -> Structured Data > Upload Default Structured Data Logo and Default post image.
Once you make these two changes then this error will be fixed.
That’s it for this tutorial!
