How do I get back my Split Login Page?

[shags38]

I use a 'customized' login page on 5 sites (works practically for me) - on one site I installed Fast Easy Checkout by Numinx however had had some issues so I have uninstalled it however the Login page loading now is the stock standard ZC page and not my cutomized page. (stock standard page also has headings issues)

I have used another site as the benchmark to check files below on the above site and all look consistent?

Aside from includes/languages/english/login.php and includes/templates/template_default/templates/tpl_login_default.php (which are identical on both sites) what other files determine the loading of the page mysite/login.html ?
