Webnus

I am constantly getting the following warnings.
I am not able to duplicate the warnings on a staging site with the same plugins and I'm at a loss what could be causing these. Any suggestions?

PHP Warning:  Undefined array key "advanced_location" in /wp-content/plugins/modern-events-calendar-lite/app/skins/single.php on line 1080
PHP Warning:  Trying to access array offset on value of type null in /wp-content/plugins/modern-events-calendar-lite/app/skins/single.php on line 1080
PHP Warning:  Undefined array key "advanced_organizer" in /wp-content/plugins/modern-events-calendar-lite/app/skins/single/default.php on line 319
PHP Warning:  Trying to access array offset on value of type null in /wp-content/plugins/modern-events-calendar-lite/app/skins/single/default.php on line 319

OK so I finally figured out these errors are caused when the location has a Location Website URL or when the Organizer has a Page URL.
If I remove the URL from both of those then no error is thrown.
A fix?
