web.config custom error settings

[AF]

Hi

I have a couple of problems and I am not sure if they are related. Our website is on a host server which has been recently set up to handle ASP .NET applications. The custom errors mode is set to "Off" even though I still get the error telling to set the mode to "Off". I've put the web.config file in a couple of different locations and get the same error. We have been told that the virtual directories have been configured as applications, so I'm not sure why we still cannot see the actual error from our side

Besides that, when the IP address is used rather than the domain name to access the site, no error occurs and the web page loads correctly

Any ideas

Thanks
