Google Docs on localhost.
error shows here.
the link was removed. I think you have now enough posts. So you can try to post it again. So you have the problem if you use the shortcode in the Gutenberg editor but not when you use the classic editor?
Can you post a screen of the browser console?
And a test sheet and a message that the file cannot be opened right now.
Please note, if it helps... using Page Builder by SiteOrigin / Kadence Theme
If I insert the Advanced iFrame shortcode via Custom HTML Block or Shortcode Block, it works.
If I insert the Advanced iFrame Block with separate settings url, height, width, etc..., it gets an error.
picture of console error is attached
What does "ith separate settings url, height, width, etc..., it gets an error." mean? Where do you enter this?
Maybe The Gutenberg block is somehow encoding/decoding which make the url itself invalid. What do you enter there. Maybe I can reproduce this.
