UPDATE: Has anyone actually identified this problem? I see it on several threads, and always there's some "solution" someone appears to discover or thinks might be responsible, and most of the threads are not resolved.
When I checked the phpMyAdmin at my host, it said the database was empty. The host support staff also told me they had no backups and no record of anything that might have been done to make the database disappear.
So is this the result of some kind of auto-updating that hosts do (one suggestion on a thread here), that databases go away for a while and then come back? Is it the sign of a bad host?
Any help, please?! I nearly gnawed all my fingernails to the nub thinking about the work that seemed to have been lost.
