I looked and there is no map on the page, but it’s hard to say why. There are several JavaScript errors on the page (F12 to open the console in most browsers), but I don’t know if they’re related. One indicates another plugin or the theme is loading the Google Maps API multiple times.
Could you please try with all other plugins deactivated and a standard theme (like ‘twenty twenty’)? If you still don’t see the map, you can contact me directly and send a login. If you do see the map, reactivate one by one to find the conflict.
You’re right – there were some things messed up in my WP in general 😛. I fixed it and now it’s working.
But there is maybe another issue: A map is shown on category and term page. Is this because the posts have maps attached, too? To hide them I used the “hide Widget” feature of WP. But maybe this is something to solve in an new requirement for Mappress, as well?
