Hi, I'd appreciate a pointer before I go nuts.
Installed the widget fine. It works perfectly with the example url, ie: https://www.semantic-mediawiki.org/w/images/8/80/20171004_Beginners_tutorial_to_Semantic_MediaWiki.pdf
But utterly and completely fails with the url I'd like to use. The complete embed code is:
<iframe height="600" width="700" scrolling="no" style="border: 0px; overflow: hidden;" src="https://littlesis.org/maps/3039-revolving-doors-from-the-uk-government-to-the-energy-industry/embedded/v2"></iframe>
which I dutifully recomposed into:
{{#widget:Iframe|url=https://littlesis.org/maps/3039-revolving-doors-from-the-uk-government-to-the-energy-industry/embedded/v2|width=700|height=600|border=0}}
If I remove the "v2" from the end of the url, I get a cute LittleSis logo in the bottom right of the iframe area - but that's it. No frame, no border, and most defo no map.
What am I doing / not doing?
