 * I just installed 2.5 with the latest build of the K2 theme. It was working great
   as I inserted custom graphics into the theme and worked through various design
   changes. Suddenly, I go to login and I receive the following error:
 * Fatal error: Call to undefined function wp_register_sidebar_widget() in /home/
   content/w/w/r/wwrmarketing2/html/wp-admin/includes/dashboard.php on line 31
 * This happened once and I reinstalled both WP and the theme and now it has happened
   a second time. I used it for awhile and days later when i go to login, it give
   me this error.
 * Is this a K2 problem or WP problem? Can anybody provide a fix? – because this
   is a very important corporate blog…Please advise…

 * It’s a K2 problem. Lots of people have reported it. Check the K2 forums, they
   may have a fix.
 * Although the fact that you said it worked and then stopped gives me pause. Things
   don’t just stop working like that. The files changed somehow. Check them against
   a clean good copy somewhere, make sure they’re all the same.
