Dear,
I now add API key. Now after save data is visible great progress (in Woredpress), but on web page still not (where at the end should be displayed). I have now only one error. I update two screens on my google drive link.
1. First image show how I setup API (maybe something is missing)
2. Second image shows only one last error in console on web page where should at the and be previewed.
Please check images.
