Hello There,
Thanks for providing the access. I have checked your site and I found out that you are using an outdated and not compatible X theme and Cornerstone version. Could you please update to the latest versions?
Our latest versions are:
- X theme 6.1.3
- Cornerstone 3.1.3
This latest release contains fixes for several issues so be sure to check out the changelog (http://theme.co/changelog/).
After doing the updates, always remember to clear all caches (if you are using WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Please let us know how it goes.
