Remember Me not working

Hi,

I’m working with this website:
https://www.areyouinmyphoto.com/

We recently upgraded the site to wordpress 2.6.3, and the remember me feature is not working — when you tick the box and log in and back out the username and password both are not preserved (both on wp-login and on the control panel on the homepage).

I’m using this plugin to theme the login page:

However, I find that even if I disable that plugin, the standard wordpress login is unable to “remember me” also.

Please help!
