WP_debug Error

I turned on WP_debug and this long error displayed.

Notice: Undefined index: ytchag_search_input_text in /www/wp-content/plugins/youtube-channel-gallery/youtube-channel-gallery.php on line 626 Notice: Undefined index: ytchag_search_select_options in /www/wp-content/plugins/youtube-channel-gallery/youtube-channel-gallery.php on line 627 Notice: Undefined index: ytchag_search_select_default in /www/wp-content/plugins/youtube-channel-gallery/youtube-channel-gallery.php on line 628 Notice: Undefined index: ytchag_search_select_show in /www/wp-content/plugins/youtube-channel-gallery/youtube-channel-gallery.php on line 630 Notice: Undefined index: ytchag_prev_text in /www/wp-content/plugins/youtube-channel-gallery/youtube-channel-gallery.php on line 644 Notice: Undefined index: ytchag_next_text in /www/wp-content/plugins/youtube-channel-gallery/youtube-channel-gallery.php on line 645

I do see this plugin has not been updated for a long time. Is this still been maintained?
