I am finding that JCE sometimes allows and sometimes disallows iframes. When I enter this code for a youtube video, it is allowed, and the video displays in the article:

<iframe src="https://www.youtube.com/embed/GO376G4tbGM" width="350" height="197" title="YouTube video player" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="allowfullscreen" frameborder="0"></iframe>

However, when I enter this code for a video hosted on bunny.net the video does not display on the front end unless I surround the code with {source}{/source} tags (from the Regular Labs Sourcerer extension):

<div style=" position: relative; padding-top: 56.25%;"><iframe src="https://iframe.mediadelivery.net/embed/108305/e065adfe-03d2-4c32-83d7-515ec9c70ccc"
style="border: none; position: absolute; top: 0; height: 100%; width: 100%;" loading="lazy" allow="accelerometer;gyroscope;encrypted-media;picture-in-picture;" allowfullscreen="allowfullscreen"></iframe></div>

I have enabled the iframe option in the Plugin Parameters > Media Support section of the relevant JCE profile (see attached screenshot). Any help or guidance would be much appreciated!

Thank you for your reply, Ryan. I have tried what you suggested, but the problem remains: it works with {source}{/source}, but not without those codes. Here is my code (with the {source} tags):

{source}<div style=" position: relative; padding-bottom: 56.25%;"><iframe src="https://iframe.mediadelivery.net/embed/108305/e065adfe-03d2-4c32-83d7-515ec9c70ccc" style="border: none; position: absolute; top: 0; height: 100%; width: 100%;" loading="lazy" allow="accelerometer;gyroscope;encrypted-media;picture-in-picture;"  allowfullscreen="allowfullscreen"></iframe></div>{/source}

Without the {source} tags I get the display shown in the attached screenshot.

No, not even when I include the {source} tags.

I have sent the details.

Thank you so much, Ryan. That seems to be a very simple solution. I'm not sure why I didn't try that.

Best regards
Bruce
