Hi @gnl,
If you are using DF 2.4 or above , then in DF admin panel :
- Click on "Services" Tab, then
- Click on "User Service", then
- Click on "Config" Tab, after that
- Select "allow open registration" , and keep all other fields as blank, and then save it.
- clear the cache ( Go to "Config" tab ==> click on the "Cache" ===> click on "Flush system wide cache").
- Refresh and then test it. Hope it will work.
