When trying to save edits to page content with Cornerstone, I am getting a 403 response, error message “Cookie nonce is invalid”, on the route /wp-json/themeco/data/save?_locale=user
I’ve disabled all plugins and even changed my theme back to Twenty Twenty default with no success.
Here is my setup:
- X theme 8.3.3
- Cornerstone 5.3.3,
- WP 5.7.2
- PHP 7.4
Has anyone ran into this issue before?
