Cannot update/add events with plugin enabled

We cannot add new events or update new events with the plugin enabled. It was working fine until now and we have to disable it if we want to add anything new or update. When we try to update we see the following errors: Notice: Undefined index: nd_options_meta_box_location_coordinates in /var/www/wp-content/plugins/nd-shortcodes/addons/locations/metabox/index.php on line 60 Notice: Undefined index: nd_options_meta_box_location_title in /var/www/wp-content/plugins/nd-shortcodes/addons/locations/metabox/index.php on line 63 Notice: Undefined index: nd_options_meta_box_location_sub_title in /var/www/wp-content/plugins/nd-shortcodes/addons/locations/metabox/index.php on line 66 Notice: Undefined index: nd_options_meta_box_location_description in /var/www/wp-content/plugins/nd-shortcodes/addons/locations/metabox/index.php on line 69 Notice: Undefined index: nd_options_meta_box_page_color in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/page/index.php on line 87 Notice: Undefined index: nd_options_meta_box_page_title in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/page/index.php on line 93 Notice: Undefined index: nd_options_meta_box_page_margin in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/page/index.php on line 100 Notice: Undefined index: nd_options_meta_box_page_header_img in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/page/index.php on line 231 Notice: Undefined index: nd_options_meta_box_page_header_img_title in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/page/index.php on line 238 Notice: Undefined index: nd_options_meta_box_page_header_img_position in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/page/index.php on line 245 Notice: Undefined index: nd_options_meta_box_post_color in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 87 Notice: Undefined index: nd_options_meta_box_post_title in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 93 Notice: Undefined index: nd_options_meta_box_post_margin in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 99 Notice: Undefined index: nd_options_meta_box_post_sidebar_position in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 157 Notice: Undefined index: nd_options_meta_box_post_header_img in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 286 Notice: Undefined index: nd_options_meta_box_post_header_img_title in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 292 Notice: Undefined index: nd_options_meta_box_post_header_img_position in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 298 Notice: Undefined index: nd_options_meta_box_post_quote in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 350 Notice: Undefined index: nd_options_meta_box_post_quote_author in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 356 Notice: Undefined index: nd_options_meta_box_post_link_title in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 410 Notice: Undefined index: nd_options_meta_box_post_link_url in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 416 Notice: Undefined index: nd_options_meta_box_post_media_code in /var/www/wp-content/plugins/nd-shortcodes/addons/metabox/post/index.php on line 466 Notice: Undefined index: nd_options_meta_box_woocommerce_color in /var/www/wp-content/plugins/nd-shortcodes/addons/woocommerce/metabox/index.php on line 59 Notice: Undefined index: nd_options_meta_box_woocommerce_header_img in /var/www/wp-content/plugins/nd-shortcodes/addons/woocommerce/metabox/index.php on line 190 Notice: Undefined index: nd_options_meta_box_woocommerce_header_img_title in /var/www/wp-content/plugins/nd-shortcodes/addons/woocommerce/metabox/index.php on line 197 Notice: Undefined index: nd_options_meta_box_woocommerce_header_img_position in /var/www/wp-content/plugins/nd-shortcodes/addons/woocommerce/metabox/index.php on line 204 Warning: Cannot modify header information – headers already sent by (output started at /var/www/wp-content/plugins/nd-shortcodes/addons/woocommerce/metabox/index.php:59) in /var/www/wp-admin/post.php on line 222 Warning: Cannot modify header information – headers already sent by (output started at /var/www/wp-content/plugins/nd-shortcodes/addons/woocommerce/metabox/index.php:59) in /var/www/wp-includes/pluggable.php on line 1251 Warning: Cannot modify header information – headers already sent by (output started at /var/www/wp-content/plugins/nd-shortcodes/addons/woocommerce/metabox/index.php:59) in /var/www/wp-includes/pluggable.php on line 1254 The page I need help with: [ log in to see the link] the url changed on me, the URL that should have been listed is: https://welcomeclub-stl.org/event/ Anyone have any info on this?
