Please update to the latest X and Cornerstone version. X 6.0.4 and Cornerstone 3.0.4 are now available in automatic updates! This release contains fixes for several issues so be sure to check out the changelog (http://theme.co/changelog/). Please do update to the latest version. 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.
