In looking at your source I see that it references the host ads.submittersrealm.com
I can't resolve that hostname here.
When I hard code that hostname to match the address of
www.submittersrealm.com in my hosts file (66.230.170.130 ads.submittersrealm.com) then your invocations seem to work fine.
It would appear that you have a DNS problem rather than a problem with phpadsnew.
Hope that helps!
