You cannot save changes, this message has already been published
Possible reasons
This error can also occur if you scheduled a post for a specific time (e.g., 10:05 AM), then opened the post for editing before that time (e.g., at 10:04 AM), but save your changes after the scheduled publication time (e.g., at 10:06 AM). In this case, the system assumes the post has already been published and prevents you from saving your changes.
What to do?
- Duplicate a Post: Find the post you want to publish and create a duplicate of it.
- Edit a Duplicate: Make the necessary changes to the duplicate post.
- Schedule a New Post: Schedule a new post for the desired date and time.
