We have an X Theme license that has been validated in the past for our demo site, but now appears non-validated. It is listed on our Themeco license page. When I try to do so it returns this message: “Uh oh, we couldn’t check if this license was valid. Details.” The Details link only shows a Back button.
I have confirmed the url for live and staging are the same in WP General Settings, including the http:// prefix. We are running the latest version of Cornerstone (4.2.3).
