It seems like anonymous access to SP lists is an excruciating pain for all besides the security reasons. My boss wants a single form in the list be public and redirect to a thank you page once an anonymous user submits the form. I managed the redirection and submission successfully. I enabled anonymous access to that particular list. When an anonymous user submits the form, SP gives the following error instead of redirecting to a thank you page.
The data source control failed to execute the insert command.
Is it a worklow issue since the list used to be private?
