404 Login Page issue

[artech7]

Okay... I'm in the process of revamping this site http://www.oquirrharms.com/

It was in shambles before.

I was doing pretty good up until today when all of the sudden the login/Register button wouldn't work. It also fails when you go to check out an item you want to buy. You get "404 Error File Not Found

The page you are looking for might have been removed,
had its name changed, or is temporarily unavailable."

The only thing that I changed was the title of the login button from 'Login' to 'Login/Register'. I tried setting it back to just 'Login'. But it still won't work. I'm pulling my hair out over this... I also looked through the forums with similar posts, but non of them helped.

Does anyone know a thing or two of what might be happening? Losing customers over this... and it is hindering the business.

Using ZC 1.5.0
I'm using the Classic Template with a few modifications to the color and layout.
