    I created a new Sidebar for one Page and added a widget, but there comes a error:

    can someone halp me solve this problem?

    Warning: Missing argument 2 for change_widget_title() in functions.php on line 157

    Warning: Missing argument 3 for change_widget_title() in functions.php on line 157

    code in the functions.php:

    add_filter('widget_title', 'change_widget_title', 10, 3);
function change_widget_title($title, $instance, $wid){
	preg_match('/\[(.+)\]/', $title,$match);
	if($match){
		$title = preg_replace('/\[(.+)\]/',"<i class='$match[1]'></i>", $title);
	}
    return $title;
}

    Hi DonTorpedo, this code doesn’t come from the Simple Page Sidebars plugin, but the change might be pretty easy if you can replace it yourself.

    Just a warning that if this is in a theme that receives automatic updates, these changes will be wiped out by any future updates. If the code is in a plugin, you’ll want to contact the author and have them update it.

    add_filter('widget_title', 'change_widget_title');
function change_widget_title($title){
	preg_match('/\[(.+)\]/', $title,$match);
	if($match){
		$title = preg_replace('/\[(.+)\]/',"<i class='$match[1]'></i>", $title);
	}
    return $title;
}

    The first line specified that he function should expect 3 parameters, but oftentimes some custom widgets won’t pass all three parameters, which can cause the error you were seeing. The $widget and $wid parameters weren’t being used in that function, so it’s safe to go ahead and remove them. The 10 in the first line is just the priority and it’s the default, so it could be removed as well.
