Thank you for writing in and sorry to hear that you’re having that issue, commonly that issue happens if you have an incompatible versions of X, Cornerstone, and/or outdated version of Wordpress. Please make sure everything is up to date, X (7.2), Cornerstone (4.2), and Wordpress (5.3.2)
Remember to clear all your caching features (plugin, server-side, CDN, and browser’s cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
If the issue persists, please do testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
Let us know how it goes,
