I'm trying to create a staging environment for my CI based webapp.
I have configured my main CI installation to work with Development and Production environments. Now I want to have a second CI installation on a sub-domain say stage.mysite.com which acts as an staging environment.
Ho do I configure my server or CI so that sub-domains work?
It turned out that it wasn't CodeIgniter installation, it was a permission issue.
My Host throws 500 when group permission is set to writable.
After doing a chmod 755 to the whole sub-domain directory the site started working normal.
This is wiered though.
