You have to Upgrade your existing publish online entry with the latest version from InDesign as this link is from an InDesign document.
Can you please more specific as to what I have to do to accomplish this? Thanks!
What you have done is: you have published a document and embedded that document in your site. Now After sometime you have deleted that document.
Since document is deleted but your site still request/tries to fetch it from server it gets this error..
To resolve this error you are supposed to remove this widget you have placed in your site.
I did delete the widget from the landing page site and it will not go away! I am at a loss of how to get rid of it.
It was created to sit on a landing page created in Pardot, and when I go to edit this page, the widget is no longer there because I deleted it, yet it continues to show when I view the page.
