I've been trying to get an SC web store up and running on one of our environments, but whenever I try to go to the web store URL it keeps redirecting me to the checkout domain (to the login page, to be precise) and then it goes to my account. I cannot even go to Home after this, even if I try to change _my_account.ssp_ to shopping.ssp manually We have created an http domain record and associated it to the SC SSP Application and web site I've also defined field sets, and setup basic required fields in web site setup. What can be the issue here?

Might be a stupid question, but you haven't enabled "Log In To See Web Store" on this domain, have you?

You mean "Password protect the entire site" in web site setup? That has not been enabled.
