My application cannot connect to my database

If your application cannot connect to the database you should make sure that:

• Your application is using the correct MySQL hostname: localhost
• Your application is using the correct MySQL database / username / password.
• Don't forget to specify your MySQL username and database with the prefix yourusername_ in front of its given name. For example, your cPanel username is lowaire and you have named your database joomla. In this case you have to refer to your database as lowaire_joomla;
• MySQL works on the default TCP port 3306.
