Hi There @justinc777
The issue seems to be that is because you're using an older version of Cornerstone plugin, so that our validation process will not be initiated correctly.
Try deleting your Cornerstone plugin by head over to WordPress plugins section, then head over to X -> Validation section and wait for few seconds to install the latest version of Cornerstone plugin automatically. Then try to re-validate your site.
If you're still experiencing this issue, provide us with your WordPress login credentials in a secure note to check your issue further.
