"The page isn't redirecting properly" - when maintenance is on

Using version 1.39h

In my case maintenance is NOT on and still I get the redirect error message in both Chrome and FireFox.
I have two ZENs running . each on a separate folder. Would that cause a problem?
Did not use to do this, it started all of a sudden.

Any idea what needs to be done?

Thanks in advance

Have you checked your admin/includes/configure.php file to make sure there are no extra forward slashes?

For example:
define('HTTP_SERVER', 'http://www.yourdomain.com/');
define('DIR_WS_CATALOG', '/folder-name/');
