I use [bgmp-map] in a widget
The url is https://www.xqyluxequality.com/
When you say :
update the function names and filter arguments, and then add the slugs of any pages/posts containing the map to $shortcodePageSlugs. If you’re using it on the home page, the slug will be ‘home’.
What you mean update function names? or filters arguments?
Do you mean slug as [bgmp-map]
And is neccessary to put “the theme name” at your_theme_name_bgmp_shortcod?
