I'm developing my own theme for one website that is operating on WordPress Network (WordPress Mu) and I had no problem with the past upgrades. After upgrading to WordPress 3.1 and using the Network Admin. I wasn't able to access to the Network Admin with my custom theme. However, when I switch the theme back to Twenty Ten, it works fine? What should I do?
Fatal error: Call to undefined function add_contextual_help() in XXXXXXXXXXXXXXXX/wp-admin/network/settings.php on line 22

I do have "setting.php" in my theme folder as part of the theme options.
Any help would be great! Thank you in advance.
