I also got the same problem. My members profiles are disappearing suddenly. It is weird, but i don't think is a hack attack, but just a misconfiguration. I looked into the Database pruning from the admin panel, and the profiles by last login would be to be deleted after 180 days from the last login. I changed that to "0" (zero) and everything looks ok now, after i re-inserted the profiles from my backup. I'm not sure if my member profiles will remain after i will switch that in future... see more Whatever, Boonex having a look over this issue may clear this for us. Perhaps is a bug!?
Hi Shaneed - I changed from 180 days to 0 days and I want to thank you for the help. When I lost the first 10 profiles I changed passwords on the remaining 60 members. This should have reset the database pruning 180 day rule but the profiles were deleted anyway. Like you say, this is a very wierd problem. I think it is a bug than can hack or bypass your password and delete your files.
