I just created a web form containing questions and answers for my website; when I click on the "Submit" button, the following error appears:
The requested page "/node/12/done?sid=20" could not be found
The error occurs is followed by this one, when I try to go to results-submissions-view, or delete submitted data.
The requested page "/node/12/submission/20?render=overlay" could not be found
I checked the permissions, and the webform settings, but I can't figure this out.
