Hi,

I am currently trying to transfer a custom application module from a DNN3 site to a DNN4 site. The main application is working fine with no problems but I am getting problems when trying to add the "Settings" page.

I have been into the module definition and added the control with a key of "Settings"
I have also selected "settings.ascx" from the dropdown box
I have also selected the Control Type of "Edit"

I get no problems when adding this information to the Module but when I then go to a page with the module on and select "Settting" from the dropdown actions menu, the control bombs out and reports "A Critical Error has occurred"

Are there any changes in the way settings controls work between DNN3 and DNN4 or can anyone suggest what maybe going wrong?

Thanks

Trev
