I was able to install YAF on localhost. I'm now trying to install it on a production server. I copied all the files to a sub-application (a directory off the main application -- the directory is marked as an application in IIS).

I was able to get to the /install/ page and complete the installation. All the DB tables and stored procedures have been created.

But I haven't yet been able to view the forum. When trying to pull up the forum, there is a NullReferenceException in the App_Code\YAF\Forum.cs file. Details below. In the yaf_EventLog table, I see the same error message everytime I try to pull up the forum.

Source: Failure Initializing User/Page.

Description: System.NullReferenceException: Object reference not set to an instance of an object. at YAF.Classes.Utils.YafContext.InitUserAndPage()

Type: 1

Any ideas are appreciated! Thanks.

I got things working. The YAF application (sub-application in IIS) was inheriting settings from the parent application. In particular, it was inheriting the setting to turn Session State off ...

<pages enableSessionState="false">

I could've explicitly re-enabled session state in the YAF web.config file, but instead modified the parent app's web.config by wrapping the section in a location tag telling it to not inherit the settings into child applications.

<location path="." inheritInChildApplications="false">
     <system.web>
	 
     </system.web>
</location>

The forums are finally coming up and everything seems to be working!
