I upgraded from 2.9.2 to 3 and am now getting this error in a few Dashboard widgets:
Fatal error: Cannot redeclare wp_dashboard_setup() (previously declared in /public_html/wp-admin/includes/dashboard.php:17) in /public_html/wp-admin/includes/dashboard.php on line 117
Thank you
three answers - One is that they shouldn't have been re-declaring in the first place. Two is a trac ticket, listing the plugins that cause the error, for 'multiple declarations of wp_dashboard_setup() causes fatal error' may not be a bad idea. Three is tell the plugin makers. If they're AWOL, you may have to make the changes yourself, though :/
