Installation and server related problems

Not sure what happened, I have updated the library but Step 2 to add interactions is not working anymore,

basically, h5p-editor-iframe is continuously growing the height attribute and showing only black content.

Since I already have created some interactive videos in my drupal platform, is there any way how I could reset h5p without losing them, to rebuild the library?

I have a feeling something is corrupted either in the database or the library.

FYI - I'm running h5p 7.x-1.34 in Opigno LMS (Ubuntu), my library:

When I am trying to insert images in Course Presentation, I get the error message: Invalid security token

I am using Chrome and have tried JPG and PNG.

Thanks

Hi all,

I have installed H5P on Drupal 8 and have created my content, which is now ready to be displayed.

I would like to have it in a view so users can browser the all my H5P, but I noticed that when creating a view, H5P doesn't offer a thumbnail or preview of the content in the teaser, so it displays the full size image or video.

Is there any way to display a preview/thumbnail of the H5P content?

Please let me know if there is any solution or if there is a better way to do this.

Thanks in advance,

Chris
