Hi again, by looking at the code of the original website (the one we are replicating now in WordPress), I can see that the code is:
<div id="grnhse_app"></div>
<script src="https://boards.greenhouse.io/embed/job_board/js?for=bagelcode"></script>
<script>Grnhse.Iframe.load();</script>
It might be that the last bit is missing. I’m trying that out now.
