Disable CB login and registration

Please see login and registration error images:

I want them to login and register only through Joomla core systems - as it was prior to paying, downloading and installing your comp.

I do not understand why you want to disable CBs login and registration. Your users will be out of sync with CB. Meaning their CB profiles will not be completely functional. Existing Joomla users can be synchronized with CB from CB > Tools then going forward they will login through CB perfectly fine.

I do not want your comp to take over Joomla Core Apps.

CB replaces Joomla profile management. That is its entire purpose. It provides substantially more advanced profiles. Many of our products do not work without CB. This includes CB GroupJive.

CB prevents direct access to Joomla user component to prevent backdoor registrations and logins. That's why you're seeing that error. You can disable this protection in System > Manage > Plugins by editing "Community Builder System plugin" then set "Redirect URLs" and "Rewrite URLs" to "Disabled".

I do not like the way your module looks. I like the way joomla's modules looks.
What I don't like: 

• Too wide
• bullet points for: 
•  Forgot your password?
•  Forgot your username?
•  Sign up

 

And I dont want to build a registration form nor profile...etc

I do not like the way your module looks. I like the way joomla's modules looks.

The module uses Joomla layouts and can be completely customized to look however you like. Many of those features can also just be turned off in the module itself. For example edit your CB Login Module then under "Login Options" set both "Forgot Login Link" and "Register Login Link​​​​​​​" to "Hide". Now those links won't display.

And I dont want to build a registration form nor profile...etc

You don't have to. Simply add your fields and you're done.

I'm not sure what you're trying to accomplish at this point. Most of our products are built around Community Builder. So they cannot work without it. If your registrations bypass it then your users will not exist in Community Builder. So you'll have to manually synchronize them for them to work with our products. They'll be lacking simple features like profile avatars even as Joomla has no such feature.

At any rate I've provided instructions for bypassing CB above. Once you've adjusted the system plugin to prevent access to Joomla user component you can use Joomla's login module and registration page if that's what you want.
