Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Our plugin doesn’t add the Schema markup in the data-vocabulary format so the websites are using a theme or plugin that is very old and it’s outputting that type of Schema that is no longer supported.
All our Schema is in JSON-LD format that is fully supported by Google and it won’t throw that error you see.
We would recommend checking the website to see what theme/plugin is creating this type of Schema and getting in touch with their support about this situation.
Don’t hesitate to get in touch if you have any other questions.
Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
