无法在wordpress页面中加载iframe

Question

I have been trying to load an section of page using iframe in my wordpress site. I can load certain sites in the iframe without any issue but while i try my required page it doesn't work as expected just inside the page. The iframe src is loading perfectly if its opened individually

I have tried most of the answers mentioned here in stackoverflow and other forums, still can't get a solution for this. I tried adding code in .htaccess, also tried adding code in functions.php

This is the iframe src I want to load.

It can be loaded individually in browser but not inside an iframe. I am getting the following error in console while i try to load it :

[ERROR] Permission denied to access property "hash" on cross-origin object

Is this an issue with my code, server config or with the URL itself?

Thanks

It's about your source is blocking unauthorization call from domains not in CORS. They're only allow call from Origin https://ec.europa.eu. The short answer, you can't deal anything from your side.
