Hello, Im newbie here. Previously when I registered as a new user it works ok but now I got an error "Selected module does not exist". Could someone help me what actually happen. For info, I can login as administrator. I have System, Private Message, CBB module installed & removed Usermanagment module. Thanks in advance.

You will need the usermanagement module, or people will not be able to register on your site. That's what the usermanagement module is for

For your info, before posting my problem I did reinstalled the Usermanagement module but somehow the new register function still does not work , so I think it might be cause by other problem . After reading your feedback I reinstalled it again and configured the preferrence for the module and works great. Thanks Herko for saving my day. BTW, I forgot to mention that at this moment I still in the learning stage using XOOPS and not yet for prime use.
