you can use this command
drush dis securepages
and then , you will have to vi or you favorite command line editor, and check if you have the these two lines, in settings.php, , comment them out: it is located in /sites/default/settings.php
$conf['https'] = TRUE;
$conf['securepages_enable'] = 1;
oh !
and while you are in here , you can check this setting , make sure it uses the right domain.
$cookie_domain = '';
and then save and quit, on vi it is :wq!
and then visit you site, this time make sure the url in the browser is http , not https.
I hope it helps
Best luck.
