Hi there that would be a user or coding error on your behalf.
Please see the documentation for the script you’ve uploaded.

As the error clearly states it is trying to communicate with a database with the username root, at 000webhost you cannot use the username root, if you hit Tools , Database Manager on our panel you can see your database username, database name and set a new password for it.

I did this but the error continues, I set up everything right database could you enter them and move?

I don’t understand?
Check your panel for your correct username and database, update your configuration files then post back with results.
