[Plugin: WordPress HTTPS (SSL)] SSL login not working

I only need the login to be encrypted; not the entire admin area. I installed this plugin and entered my shared SSL URL (https://secure.hostmonster.com/~xxxxx) in the plugin. I then added define(‘FORCE_SSL_LOGIN’, true); to wp-config. When I open test.domain.com/wp-login.php, the form action is still http://test.domain.com/wp-login.php, not https. If I manually enter https://test.domain.com/wp-login.php, the form action is still http.

If I remove define(‘FORCE_SSL_LOGIN’, true); from wp-config but leave the plugin enabled, the form action is http://test.domain.com/wp-login.php. If I manually enter https://test.domain.com/wp-login.php, the form action is still http.

For what it’s worth, If I disable the plugin and simply leave define(‘FORCE_SSL_LOGIN’, true);, the form action is https, but after submitting I get redirected to https://test.domain.com/~xxxxx/test/wp-login.php, which doesn’t go anywhere.
