Bugs in content types

I cant save my work!!!!!!! I already lost it twice because of that....I am trying to save a course presentation and it just wont save, what happened? I stayed hours working on it... Help please

While the link address appears at the bottom of the screen, the page does not display. This is in an Accordion content which I created in H5P and then embedded into Moodle.

Some content is suddenly not showing anymore
