in the wa_Globals/WA_Globals.php file, change:
$WAGLOBAL_Root_URL = ((isset($_SERVER['SERVER_PROTOCOL']) && strpos($_SERVER['SERVER_PROTOCOL'], 'HTTPS') !== false) ? 'https://' : 'http://') . $_SERVER['SERVER_NAME'] . $WAGLOBAL_localRoot;
to:
$WAGLOBAL_Root_URL = ((isset($_SERVER['SERVER_PROTOCOL']) && strpos($_SERVER['SERVER_PROTOCOL'], 'HTTPS') !== false) ? 'https://' : 'https://') . $_SERVER['SERVER_NAME'] . $WAGLOBAL_localRoot;
this will use https regardless.
