I embed an activity into a moodle page through iframe. When I save the page, the embedded activity hides all the content that was below it on the page. The code stays in place but the content itself is not shown. Please see attachments. I highlighted yellow the content that does not show and underlined the place with the embed code.
Here is the embed code itself
<div align="center"><iframe src="https://managefatigue.healthprofessions.dal.ca/pluginfile.php/1457/mod_resource/content/1/index.html" allowfullscreen="" height="700" frameborder="0" width="900"><iframe></div>
Could you please tell me what I am doing wrong?
