Iframe not appearing when logged in (Quill Theme – SiteOrigin Pagebuilder)

Hi,

I am currently trying to get a Soundcloud Iframe to work in the SiteOrigin Pagebuilder Editor field.

However this only appears when I am logged in to the back end of the site, when not logged in, the code fails to load. I know I can solve this through simply coding it, however I am looking to solve this using the pagebuilder so that I can give more freedom to the end-user and their content in the long run.

The player should appear under ‘Spotify:’ in the left column of the main content.

Any ideas?

Thanks in advance
