Activating Plugins

A plugin is not loaded until you enable it by adding its directory name to the config option plugins, as an array element. This is done by editing your local config/config.inc.php file.

For example, to enable plugins named additional_message_headers and archive, config/config.inc.php should contain this line:

    $config['plugins'] = array('additional_message_headers', 'archive');

To disable a plugin, just remove it from the list.
