Authors list

The installation wizard may warn you of several database-related erorrs. You will need to resolve these errors before you can continue with the installation.


A database connection could not be established

This error means that the database details you have entered into config.php are invalid. It may be any of the connection parameters you have specified: user, password, host or database name. Refer to the error message for a hint about what specifically is invalid.


Existing tables were detected in your database

Your MySQL server does not support the InnoDB engine
