And thanks for giving my situation some attention. The reason for emptying the trash is I was unable to add a co-domain to one of my sites; a message that it was already being used kept appearing. We may have had about four such co-domains in the trash at the time. Additionally, we were seeing entries for deleted co-domains in /etc/postfix/local-host-names file (OS is Ubuntu 9.04). I saw nothing peculiar change in the database other than the "trash-can" co-domains being deleted from the isp_isp_domain table. All custom Apache directives were still in place. I've attached a trimmed version of the log for your inspection. I see no clue why all websites were reset. Let me know if anything else will be helpful.
