here is the situation with domain xx.yy:
silverstripe 3 installed, subsites module.
A subdomain test was created. As the result, a new folder test under root was created with dummy file index.html
A/cname records created, so test.xx.yy is reachable.
So moving on tried subsites adding subsite test with domain test.xx.yy, however still get the same index.html.
Any ideas or links to what should be analyzed/updated?
