They don't even appear inside CB

That means their registration did not come from CB. It means you have another registration form available somewhere. Suggest looking into your other Joomla extensions and see if they've a registration form somewhere. It could also mean Joomla user store is throwing a fatal error and interrupting CBs registration process. That can happen due to 3rd party extensions (e.g. Joomlas contact user plugin can do this since it requires Name to be unique).

Sorry, I meant it does not appear in CBSubs, but it does appear in the CB user management list.

I'm thinking maybe Kunena? That is the only other extension where the user and membership are so integrated.
The "User - Contact Creator" plugin is disabled. I also have RSForms, but I don't think that affects user accounts.

So far it's a mystery. I'll see what I can find out and if it happens again.

They'll appear in CBs user management, but they won't exist in CBs database, if they were created outside of CB. Running user synchronization in CB > Tools will sync them back up and if you see that it synchronized any users when this issue happens then you'll know it was an outside registration.

Next time it happens, I'll do that. I have since deleted the mistaken registrations.

Yup, that'd be one way they could be registering from outside of CB. Be sure Kunena is configured to integrate with CB so it just sends them to CB registration/login.

Kunena had an update not long ago. I wonder if it's related?

I'd checked everywhere I could and for some reason, I am still getting people signing up and not being placed into one of the plans I set up in CBSubs, including a free one.

The users are able to register but are placed in the "Registered" user groups rather than the "free" plan I set up.

I was thinking of changing the "New User Registration Group" to my Free CBSubs user group instead of "Registered" in the User>Manage>Options setting. Should that have any effect on the issue I am running into?



- I have set the "Allow User Registration" to "Yes, Independent of CMS 'allow registration'"



- I have set CB Registration settings/ Allow Free Registered Users (without subscriptions) to "No"



Thanks!
