I have an ASP.NET 4.0 webapp that runs fine locally on IIS 7.5 and Windows 7. But when I deploy it to a Windows Server 2008 R2 server and try to hit a page, all I get is blank. When I view source I get this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<META content="text/html; charset=windows-1252" http-equiv=Content-Type></HEAD>
I tried creating and hitting a simple html page in the root of the webapp. Same result: blank.
I tried hitting a nonexistent page, just shows blank--no 'page not found' error or similar.
At first I had a web.config error, and that error was displayed through the page. Once I fixed that config error, I just get the blank page.
Here's what I've already verified:
IIS 7.5 is installed and running
ASP.NET & static content server is installed
Friendly HTTP error messages are disabled, so I should see real error messages from server
custom errors are disabled via web.config
permissions are wide open on the folder containing the asp.net files
