I customized the file app\design\frontend\base\default\template\checkout\onepage\login.phtml to hide the login fields in onepage checkout. It works well in 1.5 version.

When I do the same modifications in 1.6 version, nothing changes in the frontend. I observed that in 1.6 version, onepage.phtml is not using onepage\login.phtml unlike in 1.5. I did the basic checks of file location mistake(base\default and default\default) and cache refresh.

I am having trouble figuring out which login.phtml is being picked up in onepage.phtml in the line getChildHTML(’login’) [to display the login fields in checkout step 1].

Thanks in advance.
