Dear @pennywilliams,
Thank you for contacting me and sorry to know that you lost your drafts.
Deleting drafts can be happened in two cases:
1) You cleaned them manually and explicitly
2) You set up a scheduled task to clean automatically all unused elements including drafts.
Are you sure that you have not created a scheduled task by the plugin? Please verify in your “Scheduled tasks” tab if there is a “aDBc_clean_schedule” cron job? If so, please delete it to avoid your drafts from being cleaned next time.
To recover your lost drafts, the best solution is to recover your database from a backup, or you can simply import your sql file in an empty new database and then search for drafts and retrieve their contents. If you have a backup of your database with drafts I can help your recover them. Please let me know if you have a backup. Please contact me at: sigmaplugin(at)gmail.com for further discussion about this issue.
(Since many users have reported problems with drafts, I will eliminate them from being cleaned in the scheduled task)
Best regards.
