I am running BlogEngine.net as a child application inside a ASP.NET 4.0 site on IIS 7 Integrated mode. Since I Upgraded the root application, the blog does not work anymore. Browsing the blog's root url results in a 404 error.
I tried using an older backup of the blog instead of the current version, but that did not change the problem.
I even tried installing a fresh copy of Blogengine.net in that directory and I still the same a 404 error.
Installing the blog in a different directory as a regular web application (not child application) works as expected.
Please help! I am almost desperate enough to resort to using a proxy server! :-)
