Hi @CultureLinkWeb,

Thanks for reaching out.
It seems that the X theme has not been updated to the latest version but the Cornerstone has been updated to the latest version. The issue you are having might be due to the incompatibility between X and Cornerstone. I would also suggest you follow the below steps while updating the X theme and the Cornerstone.

1. Delete the Cornerstone existing one
2. Update the X theme to the latest version on automatic updates, if it is not already updated to 8.0.10 already
3. After deletion of the Cornerstone, please use the link in the dashboard to automatically install the Cornerstone.

If that does not resolve the issue, I would suggest you troubleshot a few common issues on this.

1.Plugin Conflict
2.Theme Update related issue
3.Child Theme Related issue
4.CSS/JS Customization
5.Disabling CDN

If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
If none of the above helps and you are still getting the issue, please provide login credentials for your site in a secure note to examine it further, including:

– WordPress Site URL & Login URL
– WordPress Admin username/password

To create a secure note, click the key icon underneath any of your posts.

Note: A few hours ago we have released another version of the theme with some fixes, I would recommend you to update your theme to the latest one.

Thanks
