Bugs in content types

Hi,

One of the resources I created a few months ago has stopped working. 

https://www.macs.hw.ac.uk/tel/resources/history-tutorial/

When i fill in a couple of blanks then hit "Check" the browser (chrome or safari) becomes unresposive.

I'm using wordpress with H5P plugin.

I can't see any obvious errors, and strange that it did work, but now doesn't.

Best regards,

Lisa

I installed "speak the words" on Moodle a few months ago and it worked perfectly for a while. I hadn't checked for a couple of weeks and now it does not seem to be "listening" - it doesn't record the voice! Can you help?

Hello,

I am using Wordpress, h5p content is mostly viewed trough the small devices. Latest content and plugin versions.
