I can't seem to get the User register form to honor settings in Custom System Messages.
I had this issue before (see: CSM & Solspace User) and was supposed to be fixed in the recent new release of User.
The new release seems to have fixed other forms but not the register form.
I have tried setting (12) Registration Form (On Error) & (13) Register Member(On Error) to redirect to a specific template in CSM, but I always get redirected to the General Error template.
Any help is appreciated.
