WordPress 2.5 and K2 Sidebar Problem. I just upgraded my WordPress Version up to 2.5 and I am using K2 RC4. Now there is only one Problem concerning the Dashboard. Whenever I push that Button or Login into the Administration Area I get the following Failure:
<strong>Fatal error:</strong> Call to undefined function: wp_register_sidebar_widget() in /.../.../.../wp-admin/includes/dashboard.php on line 31
I need help. There might be a problem with the K2 Sidebar Manager. Cause when I use another Theme the Dashboard works perfect.
