Wordpress PHP Error

[wolf693]

I have had Wordpress installed on my account for the past few weeks. Upon installing I recieved an error and I upgraded my PHP version to v2. I was able to successfully install it and continue working. Now, whenever I try to login, immediately after I click "Login", I get the following error message;

Fatal error: Call to undefined function wp_register_sidebar_widget() in /home/wolf693/public_html/wp-admin/includes/dashboard.php on line 31

I'm not sure why this would be happening. I have been able to successfully login without getting this error message. I looked at that location and on line 31 I have the following text;

 wp_register_sidebar_widget( 'dashboard_recent_comments', __( 'Recent Comments' ), 'wp_dashboard_recent_comments',

Do I need to upgrade to v3 or is there something else I need to do?

Reupload the /home/wolf693/public_html/wp-admin/includes/dashboard.php file.
The wp_register_sidebar_widget() code is missing.

Okay, thank you! It's working now!
