Hi,

We're in the progress of migrating from umbraco 7 to 8. We are trying to use the same memberbase as in 7 by using the SqlMembershipProvider (asp.net). The members are showing in the list ("All Members") in umbraco, but when clicking the user to edit him/her we get an error. Anyone know what's wrong, or have any suggestions?
