Getting Error 404.11: double escape sequence error

description

I have just ported my site to a new server, which is running IIS 7. The DasBlog version I am running is 2.3.9074.18820.
 
When I click on an article link (e.g. http://www.healthquotes.ca/blog/2009/09/21/2010+Vancouver+Olympics.aspx) I get the following error: "HTTP Error 404.11 - Not Found
The request filtering module is configured to deny a request that contains a double escape sequence."
 
I don't see a double escape sequence though.
 
Help!! :)

I had this happen to me as well and it's because of the "+" characters in the URL. This particular StackOvervlew question & answer were very helpful for figuring this out: http://stackoverflow.com/questions/1453218/is-enabling-double-escaping-dangerous

You just need to update the web.config as described.
