Hey DotNetNuke Fans,

I'm fairly new to dotnetnuke. I created an application using dotnetnuke with 6 custom modules. When I uploaded it via ftp to the production server, the error

"Value cannot be null. parameter name: type"

appeared on the initial load. I tried uninstalling all the custom modules, and then re-uploading the application but it did not work. Any help would be appreciated.

Thanks in Advance.

It appears that checking the Active Directory option causes this error. Check this thread. I also had this problem and that was the cause of it.
