I'm working on a small site that is using some very similar but different page types for each of its 4 pages. Because we host many small sites we use domain mapper.

When I was developing and using our main domain each of the pages seems to be using their respect pages just fine, but when I enabled domain mapper it uses the default.php.

For example:
http://slocoastaltrail.com/get-involved...
should look like this on load
http://www.altaprojects.net/slo/get-involved...

Anyone know what could be going on?
