So I updated to the newest version of Pro on my staging site (full copy of the live site, with all plugins, and the same server, etc). Played around with the new layout builder. No issues at all.
But when I try to make changes on the live site, I get the error “Uh Oh! Failed to save” and a console error:
Failed to load resource: the server responded with a status of 403 () https://domain/wp-json/themeco/data/save?_locale=user
Any thoughts?
