I want to be able to show federated wiki pages on a Grav page.
The conventional way to do this would seem to be a simple iframe tag, e.g.
<iframe src="http://isss2019.daviding.wiki.diglife.coop/view/welcome-visitors/view/introduction-to-the-open-learning-commons-and-the-digital-life-collective" width="1020" height="960"></iframe>
However, trying this inside Grav gives a message:
NOTICE: Grav found potential XSS issues in content: 'dangerous_tags'
As a test, I created a simple page.
The iframe appears as http://systemschanges.com/test/201907_federatedwiki_iframe.html
The iframe doesn’t appear at https://systemschanges.com/test/201907_federatedwiki_iframe.html
Does anyone have any creative solutions around this issue?
Is it possible to specify a single page on Grav as http and NOT https? I had installed https://systemschanges.com as https, although I’m not doing anything particularly interactive on the site.
