To switch back to a previous version of WP Scheduled Posts, make sure to delete the current version of the Plugin from your website. Afterward, go to the bottom of this page and download your preferred version from the ‘Previous Versions’ section. Then, upload it on your website and install & activate it.
Please note that, it’s not recommended to switch back to an older version. Because some of the features might not work if you take this action. If you run into any trouble, feel free to contact our dedicated and super friendly Support Team to help you out.
