Bugs in content types

Hy,

I have some issue with loading H5P content, using with WPLMS theme. Content Disappers when I begin with my course.  So when I refresh the page it will show H5P content, as normal. Maybe this is the old issue, but I can't find any answers for this. Any help, will be grate? Thanx

Error that browser is showing:

Uncaught TypeError: Cannot read property 'H5P' of null

    at h5p.js?ver=1.9.4:339

    at dispatch (jquery.js?ver=1.9.4:2)

    at v.handle (jquery.js?ver=1.9.4:2)

Hi,

(Wordpress, firefox, last version of everything...)

What's happening with fill in the blanks?

A list of languages is appearing on the screen, under the exercise (see screenshot). 

I have tried to make it again, no change. I don't understand what to do ....

Moodle 3.3 - Chrome - Windows 10 desktop

When trying to edit the course presentation, H5P editor keeps on loading, nothing happens.

There's no problem for students to go through the course presentation in H5P but editing gives this error.

Anybody with a solution?
