cannot view resources in new context

Having a strange problem within a modxcloud developer cloud.

I duplicated my web context, and updated the context settings to allow access to the site, then cleared the sites cache, and flushed the permissions.

Afterwards when I tried to view the resources within the "front end" the site failed to load with a "this link appears to be broken" error.

I've gone all through my permissions and can't find a reason why the page wont load there, but if I move it to the main "web" context it loads fine.

using modx version 2.2.8pl

attached screenshots of my context permission settings & the error

did you change the three system settings:

"For MODX to properly function, you'll also want to define the base_url (eg "/"), site_url (eg http://sub.domain.com/) and site_start (eg 15 for resource 15) setting"

I'd also look at this: http://rtfm.modx.com/display/ADDON/ContextRouter

What defines the new context: domain name, subdomain, language?
