A few weeks ago, I was getting a blank page on WP. The only thing that support folks said could solve the problem (after trying multiple steps) was to delete and re-install completely. Today, I did that, but the fresh WP install is doing the same thing. I enabled debug mode and got this error (it was repeated twice):
Notice: register_sidebar_widget is deprecated since version 2.8! Use wp_register_sidebar_widget() instead. in /var/www/vhosts/.../httpdocs/.../wp-includes/functions.php on line 3237
I have no plugins, themes, anything. I have not edited any files, except to turn on debug mode. Any ideas?
trigger_error( sprintf( __('%1$s is <strong>deprecated</strong> since version %2$s! Use %3$s instead.'), $function, $version, $replacement ) );
