DNN 4.8.4, Forum Module 4.4.3

After upgrade from Forum Module 4.4.1 to 4.4.3, "Object reference not set to an instance of an object." is thrown when attempting to 'Edit Forum' (Admin > Manage Forums/Groups > Edit Forum). Cannot Edit Forum or Add Forum without getting 'Object reference...' error.

Here is detail from the Event Viewer. There are two exceptions happening in sequence: Module Load, then Page Load (shown here in reverse order, as listed in Event Viewer by default):

Any suggestions for correcting these errors? Thank you.

Matthias,

I was involved with beta testing 4.4.x, and I forgot that Forum Module 4.4.1 was not released to the public. I do realize the risks in using the beta builds; thank you for reminding me.

Could you please reply with link to the post you mention above, with solution I may try? I have searched, but I cannot find the post you mention. A link to the post would be very much appreciated; thank you.

I found a couple issues in my original script, please see here for updated info: http://www.dotnetnuke.com/Community/Forums/tabid/795/forumid/7/postid/247540/scope/posts/Default.aspx
