This plugin causes errors in google webmaster tools.

It is giving “This is not a valid URL. Please correct it and resubmit.” because I am using relevant links like /page/thispage/ as my links instead of including the full URL.

Like this:
URL: /our-services/pathways/
Parent tag: url
Tag: loc

It is giving me an error in webmaster tools.
