If you want to schedule a blog post that you have not yet published, please make sure beforehand, that the blog post is scheduled to be published on WordPress.
To do so, please
- Go to your post editor and check in the sidebar on the right hand side, whether the post is "Scheduled" or a "Draft".
- Click on edit and change the date an time according to your editorial scheme and click on "OK" afterwards.
- No remember to click the blue "Schedule"-button, to make sure your WordPress has indeed scheduled the post.
Now you can simply click on "Customize & Schedule Social Media Posts" to be forwarded to the usual One-Page-Editor or you choose to enable the auto-posting.
