Installation successful!
To complete the installation, please do the following:
- Download config/LocalSettings.php with your FTP client or file manager
- Upload it to the parent directory
- Delete config/LocalSettings.php
- Start using your wiki!
If you are in a shared hosting environment, do not just move LocalSettings.php
remotely. LocalSettings.php is currently owned by the user your webserver is running under,
which means that anyone on the same server can read your database password! Downloading
it and uploading it again will hopefully change the ownership to a user ID specific to you.
