since updating to latest version the live survey we have running can no longer be accessed by Public users. I have checked all settings and for some reason it now throws this error. We have sent this out to loads of people and all coming back with the same error.
I have checked all the settings and permissions etc. inside survey and nothing has changed other than the update. Is there an urgent fix for this?
UPDATE: have done numerous tests including creating new menu links to individual surveys, all permissions are correct. It seems it will only allow logged in people to take it.
