The wizard should just work, so there is no tutorial on how to debug issues that arise... that is what this forum is for.
Let's take it one page at a time. We will do: registration, login, forgot password
So first let's talk about registration. Please send a url to the page that doesn't work, and a description of what exactly is wrong. Please also attach a copy of the page so I can open it in dreamweaver to see the code.
Once we have the registration page working then we can move on to the login page.
