I made change to login_form.html to change the look of the login page.
When some click a link to save to favorites but they are not logged in it takes them to a login page that seems to be controlled by a different templete.

at login.php I get the page that reflects the changes I made to login_form.html

at login.php?f=1&b=cp%2Ffavorite_add.php%3Fid%3D3013
I get a login form that looks like the original. What template control this login form?
