DNN 435

It was a fresh new install of dnn435.

And I used the latest survey module (PA/Source) from oct06.

In the DB I get an numerous ID for the createdByID. This seems ok.

I will soon try the changes you suggested.

But have just found another error. When I tried to uninstall the module, in order to upload the new fixed zip, I got this (Meaning the uninstall process doesn't erase the 'add' tag from the web.config):
