ok my problem is, weird ..
I have version 3.0.2.0 on a host that is Hostinger. if you do not know they give you the option to install the fast opencart application.
But from what I saw the version that I install is missing a lot, has errors but corrected some, fast.
But now I need one that really has me worried and I do not know what to do.
The fact is that I was practicing with some friends on my website to see the operation, everything was excellent.
The bad thing is that the users who register do not appear in my list of clients.

in this case I have 3 registered users, but when I click to see who they are, it remains that way.

But check and notice that in my database if the users are saved. What happens there?
The other case is that I do not want the client to pass without my approval, they pass directly but I do not want to.
okay
I want to personalize payment methods, which do not exist anywhere, I look for it and nothing, I just want to know how I add that option .. it does not matter that I stay as is the option of bank transfer.
okay
because you can not customize the links? I personalize them and I get an error

okay
I want to place implement an example widgets
okay
and finally for what are the affiliates in opencart
