Admin login form not secure after upgrade

[KungFuMouse]

After upgrading to 157c (clean install) my login panel returns with an error in chrome of where if I fill in the admin details and password it returns with a form is not secure

Clicking send anyway just brings you in a loop to log in again

I have tried the install docs and the forum but don't see that specific error

Managed to fix it.

taget file admin/includes/configure.php needed to have the following line updated to HTTPS protocol

define('HTTP_SERVER', 'https://yoursite.co.za');

Encourage doing the same on the site front version of the file: includes/configure.php
Note that the file gets set or reset to read only so be sure to make it writable before trying to save your changes.
