Hello There,
Thanks for writing in! Could you confirm that you have updates to the latest versions?
Our latest versions are:
- X theme 6.1.3
- Cornerstone 3.1.3
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.
If you are referring to the site icons, we have migrated it to native WordPress “Site Icon” settings for cleaner brand management. You need to insert again the favicon in Appearance > Customize > Site Identity.
Please let us know how it goes.
