No configuration file found.

I looked for configuration files in the following places:
/etc/gnusocial/config.php
/etc/gnusocial/config.d/trythisout.co.uk.php
/etc/gnusocial/config.d/trythisout.co.uk_Demo.Gnusocial.php
/var/www/trythisout.co.uk/htdocs/Demo.Gnusocial/config.php

You may wish to run the installer to fix this.

Go to the installer.
