Reinstall H5P plugin without losing the content
I've recently got a lot of problems after updating the h5p plugin and their libraries. I am using H5P 1.15.3 running on Wordpress 5.7.2
One of them is: the Course Presentation Editor doesn't work at all. I am getting this code [field:group:coursepresentation:presentation] instead of editable presentation. The browser console (Chrome, Firefox) shows me a bunch of error messages like " Uncaught TypeError: Cannot read property 'prototype' of undefined..."
I would try to reinstall the plugin. how can I prevent losing the created content?
