I have DNN 4.00.02 with 3.20.01 Forums installed.  I enabled attachments and tried it out.  After browsing to a jpg, I clicked on "Add".  Every time I then get the following exception:

Exception Details: System.ArgumentNullException: Value cannot be null.

I don't think I ever tried attachments in 4.x.  I will try this out tonight and get back to you.

Hey Crispy - Did you get a chance to look at this?  If not I'll look into testing out my debug environment to repro the bug.

I tried adding an attachment, the post went through fine but no attachment was present in the UI.  For some reason it is not sticking.  I will look into this, but right now I bet it will prove to be difficult to track down due to the module not being in a 2.0 ready dev enviroment.  We were able to find fixes before but they also proved to be difficult, but fixable.

I finally got my DNN source environment up and running, but haven't figured out how to add Forums Source to the project.  Any advice?  I'm using VS2005.  Once I get forums under the debugger it should be a lot easier to point out where the code issue is.

Thanks,

James
