Are you using the Joomla login or a login for an extension, like a social extension? A blank page typically means a php error, you need to enable Error Reporting in your Global Configuration settings to see the error message.

The 40,42,45 code line in utils.php is :


40 $side_column = ($this->countModules('left')>0 or $subnav) ? $side_column : "0";

42 if ($template_width=="fluid") {
$template_width = "width: 95%;margin: 0 auto";

I see the errors when I try to login, I also tried your admin but your admin folder is password protected. The errors are template related, it could be your template is not compatible with the new version of Joomla. It could also be that there was a modified Joomla file that was needed for your login but the update replaced it.

You could try switching templates and test to see if front-end login works then.

Your admin login may be due to the new security that the Joomla update adds, if you had a security extension installed it could be that it is not compatible with the new Joomla update.
