Iframe not working – SAME ORIGIN issue

Hi guys

So i had an i-frame in one of my pages set up to an external site on a different domain, but it seems to have stopped working. I’ve used chrome and inspect and found the following:

Refused to display ‘https://www.macronlondonsoutheast.com/horwich-rmi-harriers-346-c.asp’ in a frame because it set ‘X-Frame-Options’ to ‘sameorigin’.

Just wondering if there is a workaround for this?

Thanks
