Request was rejected because user is not permitted to perform this operation

I am running the latest version of ghost (3.40.2) on a DigitalOcean Droplet with Cloudflare.

When I try to edit an old post I get the error (when pressing the “save” button):
“Request was rejected because user is not permitted to perform this operation.”

The error appears only on old posts, it works well on my 4-5 most recent posts.

I guess it is a permission issue? However I checked for permission issues with ghost-cli and everything seems alright.
