I created a WFFM in my sitecore instance and then set save action "Create User". The scenario is that a layout page will be displayed if the action succeeds.
When I run the form by mode "preview", after the submission, this error "**Most likely causes: The resource you are looking for (or one of its dependencies) may have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. **" has been launched. I can not detect something wrong I did manually configure.
P/S: sorry to post only the photos, because I only want to tell you all of my steps I did
