I have used jomsocial with jomsocial profile type.But when i try to regiter it gives me "Unknown class CFieldsProfiletypes for field profiletypes. " error.
Profiletype is in group.
And in backene i can not be able to see the field type as profiletype.
Please help me to solve this problem. Thanks
In Backend -> Components -> JomSocial -> Configuration -> Customize profiles, check if all fields are associated with any group.
This errors often pops up if fields are not associated with any groups.
