MyBB Documentation

Configuration File

During the installation process of MyBB a inc/config.php file is created with the following content, where:

  • provided database connection details are saved in $config['database'] (Database configuration),
  • provided Table Encoding is saved in $config['database']['encoding'] (Database Encoding) — in this example: utf8,
  • provided ACP PIN is saved in $config['secret_pin'].

Consult the MyBB security guide to correctly configure security-related values.
