Hi @pollenbird,
I have checked your geologists’ association site, it seems you updated the Cornerstone to the latest version (4.1.2), but you leave your X theme behind (6.5.5). Please update your X theme to the latest version (7.1.2).
Updating Your Themes and Plugins
Another thing, your Wordpress is also a few updates behind, please update your Wordpress to the latest version as well to ensure compatibility.
Updating WordPress
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.
Let us know how it goes,
Cheers!
