At point 2, maybe is you telling mi that the free hosting doesn't work with MySQL databases?
Yes it does, only you have no root access to it. I mean, you don't have access to anything else outside your DB name and MySQL commands.
1044 Access denied for user 'id2179606_susy'@'%' to database 'id2179606_dbmaple'
This error strongly means your database credentials are incorrect. Or that something else is incorrect...
- How many databases do you have?
- How many accounts do you have?
- Are you trying to access the database from an account with the website from another?
