Hello David,
Thanks for writing in! Could you please update to the latest versions?
Our latest versions are:
- X theme 6.1.6
- Cornerstone 3.1.6
This latest release contains fixes for several issues so be sure to check out the changelog (http://theme.co/changelog/).
Make sure that all your other plugins and WordPress core are up to date too. Most of the time, out dated WP or plugin may cause issues in the site which can also be the reason for loading problems.
_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.
