Bugs in content types

When I view the official H5P site's Audio Recorder page in Chrome I see the audio recorder and it seems to function as expected. On my client wordpress site the Audio recorder is not showing on the page.  I do see there are some javascript errors happening, and they go away when I remove the H5P audio recorder shortcode. 

The errors indicate a security issue that the page is detecting, so that is why it is not showing the content. I'm not sure how to fix this.

I have updated all plugins and theme, and the WordPress Core is up to date.

Making my first Course Presentation and running into a display glitch with text boxes.  If you look at the attached file, you can see that the red word "Introduction" is cut off at the top (the "I", "t", "d", and "i").  That text is formatted as <h2> but it is also enlarged to 225%.  The bounding box for that element isn't giving enough padding on top to display the text completely.

Hi

First of all, thank you for your amazing plugin!

I've got a problem with 'Speak the words'. I can insert it in a post but when I try to record my voice, I click the button and nothing happens.

I'm using Google Chrome and my plugin is installed in Wordpress.

I don't understand what I'm doing wrong because when I go to your demo page, it works. I noticed that a message asking to use my mike appeared, which is not the case when I want to test it on my site.

I hope you can help me

Thank you in advance for your answer
