Custom Registration Page Divi

[ Moderator note: moved to Fixing WordPress. Please do not use Developing With WordPress for these topics. ]

So I’m trying to make a custom registration page but I’m having a heap of problems! I’ve tried every plugin imaginable but to no avail, they all either cost money, make WordPress crash, or don’t have the usability I need. All I want to do is have a page that is off limits to everyone unless they have a teacher account(that’s something I need; the ability to create custom roles)

I just need to be able to make a custom registration page that assigns the role to teacher and records their information (I need custom info, so I can’t use the default) then once they’re logged in to be able to view that page. Are there any really simple ways to do this?

I’ve tried ultimate member, it just crashes WordPress
