Thank you for replying @michiel!
Sorry about my silly question,
I followed the steps in above link and removed the following lines from bitnami-apps-prefix.conf and added in bitnami-apps-vhosts.conf and restarted.
However, when I went to blog.socialchamp.io, it didn't reach to my WP Blog and showed me this page.
My assumption is that I'd have to define configuration of my blog too into bitnami-apps-vhosts.conf just like the below was done,
# Bitnami applications installed in a Virtual Host
CustomLog "logs/yourdomain.com-access_log" common
How can I find the right configuration of the pre-installed blog settings, having the SSL conf too? I quickly checked httpd-app.conf and found some settings but wasn't sure if any certain tag was to be picked and pasted in bitnami-apps-vhosts.conf
Thanks a ton!
