After a long drill down I figured out that it is this custom code I entered in a functions plugin, to improve the PageSpeed Insights result:

Any way to get it to work despite of this? I needed a long time to optimize my PageSpeed result.
Hi, you are right, if I deactivate all plugins it works. But I need them all 🙂
The developer console shows “ReferenceError: MapSVG is not defined” (“…/wp-admin/admin.php”).
Thanks and regards, Alex
Hi Jennifer, thanks! 🙂 I will follow it there.
Hi Jennifer,
in case you find a solution to this over time, I would be super thankful if you could post it here. For me it also doesn’t show..
Best regards
Alex
