This file should be empty by default. So it's ok.
You will need to comment out (adding
#) the follwing line in
Also make you sure you add in your VirtualHost definition (
/installdir/apps/mediawiki/conf/httpd-vhosts.conf) the following line:
Then as mentioned, add your domain to your hosts file and restart apache.
If you run into issue paste me your bitnami-apps-.conf files and your httpd-app-.conf files.
Hope this helps.
