Wikka Configuration Options (wikka.config.php)

See also
The table below lists the configuration options available in the wikka.config.php file. The wikka.config.php file is generated by the installer when installing Wikka for the first time and when upgrading from previous versions. It is intended to be edited only by the web site admin only, because it contains sensitive password information and crucial configuration options for the operation of Wikka. You can use a FTP client to edit this file on your web server.
