i had the same issue (although my site is still not working, but at least it successfully debugs). You have to re-create your project. In the project creation dialog, select v3.5 from the drop down list at the top. It is very important you do this at the creation of the project, because simply downgrading the framework in the properties dialog doesn't work (I don't know why). When the target framework is set correct, you will get another web.config file, without that attribute. In my situation, i could then debug the project successfully (local), but unfortunately my site is not working. I keep having the same error as you started this thread with, how did you solve that one?

I can't find support on this problem anywhere, so i thought i would post it here. When I try to upload a standard vs2010 ASP.NET Webforms application to my site's public_html folder, all I get is a server error: Server Error in '/' Application Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. ... and so on. And because of those security reasons, I can't see the details of that error, and so I can't solve it. I don't even understand why there would be an error, because it's a vs2010 template (not edited), which I uploaded right away, just to test if everything is working. I already checked my target framework (which I set to v3.5), so that is not what is causing the error. If someone from the Heliohost staff could give me more details about the error, or someone with experience uploading ASP sites could tell me what is going on, that would be really appreciated. Thanks in advance, DeepBlue
