Undefined offset: Notice on front end

Hello!
Not really sure where that’s coming from; the referenced line is where the plugin gets the options for the widget, it might be the widget no longer exists or some corruption in the saved data for the widget? Please try adding a new instance of that widget to the Arbitrary widget area and use that one instead, see if it shows the notice message.

We noticed this one on a customer’s site as well. I’m not sure how the widget data is getting corrupted, and it could be a symptom of a bigger problem on the site. But I was able to patch the code like this around line 130 of init.php to avoid the notice:

if(!empty($wp_registered_widgets) && !empty($wp_registered_widgets[$widget_id])) {
	$options = get_option( $wp_registered_widgets[$widget_id]['callback'][0]->option_name );
	$instance = $options[$number[0]];
} else {
	$instance = false;
}

You might want to consider doing something like this here.

I suspected the issue might be due to widgets that have no options at all, try as I might however I did not get that notice message. However added some conditions for the new update to make it smarter and the notice message should go away ??

Thanks Shazdeh.
