I accidentally deleted one of my user account which do not contains any html files but has 3 databases files. I though it was an empty account and deleted it. 3 days later my colleque told me that it has 3 important database files.
If I deleted the account, doest it means the database also deleted? Is it possible to retrieve it? If yes, how?
Unfortunately deleting an account deletes anything and everything associated with that account. Do you have any backups such as a reseller backup, or admin level backup? If so you will be able to restore those databases but without a backup, your out of luck
