I had this issue in the morning. But when I tried what I've been told to do by checking db on /mysql/ folder and them store it. And move to another mysql with another account and restore db with same folder as above.
Now my issue is the following:
I took the backup-ed files into a new folder and created a db with the same name. The tables are now seen inside the database but when I click on a table, it said table does not exist.
