PHP Notice: Undefined index

Hi P?r Thernstr?m.
What your plugin and wordpress version?
We turned WP DEBUG on and it works OK with latest version of WordPress.
Please check again with latest wordpress and plugin.

WordPress 4.1.1 and plugin version 2.6. I deactivated all other plugins and made twenty twelve the default theme. Still get this error on page load, when editing a post:

[14-Mar-2015 20:15:47 UTC] PHP Notice:  Undefined variable: pw_class in sitename.local/assets/plugins/wp-page-widget/wp-page-widgets.php on line 476

And when adding or changing the widget order I get this:

[14-Mar-2015 20:15:57 UTC] PHP Notice:  Undefined index: tag_id in sitename.local/assets/plugins/wp-page-widget/wp-page-widgets.php on line 991
[14-Mar-2015 20:15:57 UTC] PHP Notice:  Undefined index: taxonomy in sitename.local/assets/plugins/wp-page-widget/wp-page-widgets.php on line 992
[14-Mar-2015 20:15:57 UTC] PHP Notice:  Undefined index: search_page in sitename.local/assets/plugins/wp-page-widget/wp-page-widgets.php on line 994
