I’m just trying to embed content on a page using the HTML block with an iframe. However, every time I save the iframe code is removed from the HTML block. Any help is appreciated, thank you.
The content I’m trying to embed is not embeddable via oEmbed or a Media Embed, unfortunately.
How are you hosted? This is possible according to the manual, we’ve used it on our institutional site without (to my knowledge) any customizations, and I’ve just tested it on my personal (Reclaim Hosting) install without any specific customizations to allow iFrames that I can recall or locate right now.
I believe you have to disable the HTMLPurifier in the Admin Settings to allow embedding iframes (see Settings - Omeka S User Manual ), otherwise, the iframe will get stripped out.
