We have recently put up a new server with IIS7, where we now have published a .NET4 site.
Locally everything works fine, but on this server the Default.aspx is not working. No events are firing at all for this page. Every other page works as should.
We've tried deleting the Default.aspx and adding a new blank one with just a button event but same thing still applies.
We've spent quite some time troubleshooting this without any results. Same problem exists both with and without using a masterpage.
Any help appreciated.
