Default aspx webpage

I am working on my first aspx application using Visual Studio 2010 Express and ASP.NET 4. I have uploaded my application and set the Default aspx page in the web.config file as well as setting the Default page in the Control Panel under IIS Tools > Default Documents. When I type in my domain name (www.website.com) I get an internal error 500.19 (The related config file for the page is invalid), but if I type in the full Default file path (www.website.com/appname/Default.aspx) everything works fine. I am sure it is a simple fix and I'm just an idiot, but can someone point me in the right direction? Thanks!

 

That error is probably due to an error in your web.config setting. Probably recommend starting it from scratch to determine the cause of the problem.

 

Jose,
Thanks for the recommendation. I started with a new web.config file and it works great!

 

Nice. Glad you got it working.
