Bugs in content types

I am using the exportable text function for a Course Presentation and for some perculiar reason the export button has disappeared entirely from the end of my presentation! It just shows a blank slide. I have tried multiple browsers (tested in Chrome, Firefox, IE). It was working last week (31st August 2017). Please help!

Hi how are you doing??!!

I installed H5P in WP 4.8.1 and with the drag-and-drop activity, when I add the background image it does not show it to me.
I have read that there may be problems with the path to the image.
How do I solve this problem?

Hi how are you doing??!!

I installed H5P in Moodle 3.1 and it works fine, the only problem I encounter is that for the drag-and-drop exercise, the background image is displayed by taking up the full width of the screen and does not respect the predefined size in the configuration (800 px).
How can i fix this?
