Hi There @rpijut44
Thanks for writing in! I have checked your site that you have assigned to this Themeco license. The issue is that you're using an older version of Cornerstone plugin with the latest version of X theme, so that our validation process will not be initiated correctly.
Head over to WordPress plugins section, then disable and delete your Cornerstone plugin first. Then head over to X -> Validation section and wait for few seconds to install the latest version of Cornerstone plugin automatically.
Once the latest Cornerstone plugin is activated on your site, try validating your site again and it should work.
In case if you're still having issues, check our troubleshooting guide here (https://theme.co/apex/forum/t/troubleshooting-validation-connection-issues/201). If you cannot resolve the issue, provide us with your WordPress login credentials in a secure note to investigate your issue further.
