Installing an old application to a new server

Ok, it looks like you're not using a virtual host configuration. I'd recommend it, but it is more complex.

I have all my sites under /var/www/ like this:
/var/www/
|
+mysite
+othesite
+theirsite

In the apache virtual setup, I use the virtual host to avoid using localhost in the url
/etc/apache2/sites-available
and
/etc/apache2/sites-enabled

These are where you create the apache configuration for sites using full domain names etc.
The configuration is complex and I'm not going to try to walk you through it here.
Reference: http://httpd.apache.org/docs/2.0/vhosts/name-based.html
and: https://httpd.apache.org/docs/2.2/vhosts/examples.html
and: http://www.thegeekstuff.com/2011/07/apac...tual-host/

I'd recommend moving your site code to /var/www/yoursite instead of elsewhere, since you're in a local environment. It makes working on it easier.

Sorry for the overload of information, but it may be at the root of the problem, not pun intended.
I'm available on this forum to help you through it, as are several others here.
