I have a really weird problem. Somehow it seems ispconfig deleted all my website files. I have numerous websites located in /var/www/web*. After emptying the trash folders in the ispconfig admin backend and running "repair database" I found that all my websites were reduced to their default status with a single index.html file and an "error" folder. No trace of any files whatsoever Luckily I have backups of all sites, but I'm still confused - any ideas how I could troubleshoot this issue and find out what happened to all my files?
