I am hosting BlogEngine.Net 18.104.22.168 and am seeing some issues with getting the DefaultNetworkCredentials property.
You can't see that off hand on the pages, but the sites fails to produce proper js scripts with js.axd module.
It fails in the lines of the code that call:
client.Credentials = CredentialCache.DefaultNetworkCredentials;
It can be seen if you run fiddler. It turns out that one of the references to jscript returns a HTTP302 that redirects to the error (HTTP404) page.
The link to the script that fails is the one:
(or some other identifier as the id generated might depend on session or maybe some other factors).
To see precisely the link that fails for you, run Fiddler (or similar HTTP monitoring tool) and look for the link that is similar to the above and generates 302 with redirect to
If you turn CustomErrors (set to Off) in Web.config for the /blog/application.
Then you will get the error page with the call stack:

As a result, the java script files are not properly generated and there are jscript errors that make some featueres fail (like posting comments).
Please, let me know what you think of the error or if you know a remedy to it.
