Bugs in content types

Hi to all and greetings from Greece!

I am trying to develop a content type for a quiz game I need for my BA in CS dissertation. After a LOT of trial and error I managed to make a Greeting Card. I am emphasizing on A LOT cause there are some problems with the tutorial provided. I'll explain:

Hi there,

We're using moodle 3.1, and in Firefox and potentially IE on desktop, when we use the accordion, clicking some links within the text cause the accordion to 'crash'; the accordion disappears from the page. Not all links are affected, but it is consistent behaviour in terms of which links do and don't cause the crash.

Is this plugin compatible with moodle 3.4?  I've never been able to get it to work on my moodle courses.  I have Moodle 3.4
