Resolved: [2005] The XML page cannot be displayed

[brucevde]

I am getting the following error on a simple project/site (it only has a master page, default.aspx, some classes and a stylesheet). The error only occurs if I browse to the default.aspx page directly. Using //localhost/testsite works fine. When running within the IDE and with the project's Start Page set to default.aspx the error occurs otherwise it works fine as well. Other projects/sites don't have this problem.

I compared the IIS settings of two virtual directories and everything seems to be in order. The ASP.NET tab is the same for both.

Running aspnet_regiis -u and then aspnet_regiis -i did not work.

The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
