It seems that Yoast SEO plugin causes shortcodes to render when saving a post in the admin. I am not sure why this is happening and if this is a bug in Yoast plugin. But because the global map shortcodes render when the page is being saved, it is looking for some files and functions that are not supposed to be included in the admin side. Because of that, you get the error message.
As a quick solution at the moment, I edited one file in GEO my WP core plugin ( directly in your staging site ) and included the files that the plugin is looking for in the admin as well.
I don’t really want to do this, but I will do as a temporary solution in GEO my WP plugin as well. I will add this to the next release. That is until I figure out why Yoast plugin does that and if this is something that needs to be fixed on Yoast side.
