Weird URL Issue

[zxh05]

Hi I am a newbie and just install the latest version of rouncube. I found a wierd url issue after installing. It seems like I cannot login to inbox using http://www.mydomain.com/roundcube/ but I can do so using http://mydomain.com/roundcube/.

For http://[b]www.[/B]mydomain.com/roundcube/ after i enter the required information, the page just reloaded and back to login textboxes.

Why is this so? I truly appreciate if anyone can help in this. Thanks

that sounds like a cookie problem to me, could you check your config ([rc root]/config/main.inc.php) and post the value of $rcmail_config['session_domain'] please?
