Hello. I’m trying to make it so that to be a member you have to pay. Right now on my site, you can still be a member without paying any money. To clarify, on my site, you should only be a member if you can pay the subscription fee.
You will need to add something like Wix Paid Plans then to get them to pay a membership fee for example.

They will still be able to sign up to your website as a site member, however you can allow or restrict access to any page depending on the users member status or user role etc.

You can also use Wix Users API to get the users info like user role too.
