You need to add the two hidden fields that I'm appending next.
<asp:HiddenField runat="server" ID="hProvidersAbilities" />
<asp:HiddenField runat="server" ID="hDefaultMembershipProviderName" />
I got caught by the first error msg, added the hidden control, but then got the same message again right away. I double checked the id and it forced me to add 2 hiddenFields.
Hope this helps someone :)
