you said it's working on your localhost, I'm assuming you ftp'd the site up to a server. Are you using shared hosting? Check the dbname, sometimes the hosting companies like to add prefixes to database names and user names

If you ask for dbname "database", many of them will create "sitename_database" or something similar. The same is true for the user accessing the database.

Check these, you may need to alter your database config file a little.

Check your hostname, db prefix.
By setting this correct, your problem will be solved.
No other issues can create this error.

Happy coding,
