Bugs in content types

Created a new post type and created new fields and removed the default WordPress content

Then I added the shortcode [h5p id="1"] into my custom post inside a custom field

the page is not displaying the audio recorder unless I use embed using an iframe.

The page looks blank and when inspected this is the only thing displayed

<div class="h5p-iframe-wrapper"><iframe id="h5p-iframe-2" class="h5p-iframe" data-content-id="2" style="height:1px" src="about:blank" frameborder="0" scrolling="no"></iframe></div>

Hi all,

Today I embedded H5P "fill in the blanks" in a page-resource and a lesson-resource in Moodle. After that, both the page and the lesson started to flicker on all my devices. The page and the lesson also contain other embedded H5P code (though in the lesson not on the same content page). The Moodle-activity "stealth mode" (activity invisible, but accessible) was activated at first, deactivated at the end, but the flickering continued.

It seems like a programming error. Does anyone know what to do?

My Moodle-version: 3.5.3

Hello Running Moodle 3.5. I've uploaded a less than 5MB video and only have 5 interactions. The activity is loading really slow and when i try to edit the interaction, i often get a 504-Gateway error. I know my comp can view mp4 files. Any advice?
