Hi All,

After upgrading DNN 3.1.0 to DNN 3.2.2 and forum 3.2.1, most of my previously working forums can not be accessed. The module page works but when I click on an individual forum, I get "Object reference not set to an instance of an object" (detailed error below). Not sure if it matters, but the only one of my forums that doesn't throw this error (i.e. it displays fine) is one that happens to have no threads.

Any ideas?

Thanks Much,
Scot.

Here is the error from the log:

Scot,

I don't know of anything that would cause this.  I would try going into manage each forum and just update the settings, then try again.  Next, I would try posting in the empty one and see what happens.

Updating the settings had no effect. When I posted to the one forum that didn't throw an error, I again got "Object reference not set to an instance of an object." (detailed error text in log has the same method as before). Trying to access that forum results in the same error as for the other ones.

Any other ideas?

Not sure if there is any relation, but my logs now also have lots of the errors below. The last one appears to be at the same method but is a different exception (general instead of page load).

Thanks Much,
Scot.

A follow-up/some other weird behavior:

The Forum Administration menu item is there but has no text (the little pencil icon is there and when I click on the space I get to the forum admin page).

The test post I made in the previously working forum shows up in the RSS feed. Following the link of that post (http://www.objectrolemodeling.com/Default.aspx?tabid=1&forumid=31&scope=posts&threadid=435) results in the main page of the portal loading (not the thread/forum page). Clicking on any old (pre-upgrade) forum post from my RSS reader results in the same behavior. I don't think any exception is being thrown when it does this.

The counts on the main forum page were updated as well.

Selecting the "my posts" link results in the same exception. Searching returns no results even for terms I know are in there.

Yesterday, I tried reinstalling the module and forcing the 3.1 to 3.2.2 upgrade again and both worked with no errors.

FYI,
Scot.

You need to check the user aliases. It seems that for some reason some of them are "" (aka nothing).  You can usually do this from the Manage Users Section or manually from the db.
