I installed yaf forum in a sub forum folder ie. \Forum\Default.aspx which is in a top level masterpage ie MasterPageFile="~/MasterPage.master" asp.net 2.0

I have turned on enableurlrewriting

<enableurlrewriting>true</enableurlrewriting>

It all seems to work great

The problem I have is that have enabled some error logging in the global.cs file and constantly keep getting the following error from various pages withing the forum app.

I can never recreate the error myself.

Error Message: The file '/Forum/forum/Default.aspx' does not exist.

the actual path is /Forum/Default.aspx

Has anyone experienced this problem, I am not sure if this is something to do with urlrewriting or not.

Here is a more detailed error.
