Hotspot user can't signup

Hello

I’ve bought a small RB750 and configured hotspot with user manager.
All is working fine, but when i go on http://wan-adress:8080/user?signup=publicID i see a page where i can only login, there is no possibility to create an account.

What i’m doing wrong ?

thanks

Do you have signup enable on usermanager?

I’ve finaly find that on v5 firmware the link is /user/signup !
