While the plugin may have updated, the matching database changes failed to go through; however, as this update now shows as completed in your database, the matching database changes will not run through now. * This can be manually fixed with direct database changes if you are very comfortable with SQL, but the easiest path forward is to do a complete re-install of MailPoet. * I know you have previously done re-installations of the plugin via FTP, but what I’m talking about here is a wipe of all the database tables as well, and full re-install from scratch. * This will wipe all your mailing list data, so if you have existing subscribers and lists you would want to export these first, as per here: [https://kb.mailpoet.com/article/330-how-to-export-subscribers-from-mailpoet](https://kb.mailpoet.com/article/330-how-to-export-subscribers-from-mailpoet) * Then, once your data is safe, go under MailPoet > Settings on the “Advanced” tab. Under “Reinstall from scratch” click the “Reinstall now…” link. * Once again: this will erase all MailPoet database tables and data from your database! So make sure you have backed up any MailPoet data you wish to keep (and a full database backup is always a good idea too). * Once the re-install is complete, then you can import your subscriber list as per here: [https://kb.mailpoet.com/article/389-importing-your-subscribers-to-a-mailpoet-list](https://kb.mailpoet.com/article/389-importing-your-subscribers-to-a-mailpoet-list) * And that should do it.
