I want to follow up on the issues from last week - all of May's content disappeared from the site. We do have daily backups however for reasons that are still unknown the backup didn't include that content either. Eventually the hosting company located a backup with all the missing content and they just restored it. Unfortunately all of the content from the past 6 days in June has been overwritten, including any member signups.
I'll keep a close eye on the new backups to make sure we can restore from a backup more quickly in case this happens again.
Sorry for the inconvenience
