Any suggestions on how to remedy the below?
Stackpath say it is issue with code. I find it hard to believe that the inherent features of Magento1 would break though? It occurs on any of the editor forms for image upload function/button. Blank white box displays.
From Google developer console, below are errors:
Uncaught DOMException: Blocked a frame with origin "https://cdn-domain.stackpathcdn.com" from accessing a cross-origin frame. at Object.init (https://www.domain.com/js/tiny_mce/tiny_mce_popup.js:5:107) at https://www.domain.com/js/tiny_mce/tiny_mce_popup.js:5:4764
