Charts don’t show up

Hi there,
from some time now the charts I integrated on few pages on my website, are not showing up at all anywhere.
I tried multiple times to disable various cache plug-ins and excluded the page from any js minify & co.
inspecting the item on the browser everything looks fine, but still nothing is visible.

Do you have any issues with the last WordPress release?
I had a look in the forum already, but no issues like this were encountered yet.

Looking forward to hearing from you!

Thank you in advance!
