Verify that YAF is operating from it's own "Virtual Root" -- basically, you need to take the YAF folder (if it's not in the website root) and tell IIS that it needs to be it's own Application. Additionally, you need to verify that the web.config is in the YAF main folder. Also verify that proper ASP.NET version is selected...

I Publish forum from Source

Then I use IIS on windows 8, Add Virtual Directory in IIS. (dot net framework 4.0)

I am not sure this issue from IIS or file web.config..

Please help me
