all content types

1. Detailed steps to reproduce the bug (exactly how and when did it happen)
   I created a new H5P (Agamotto, but the bug exists for other types too) in the Content bank in Moodle 3.9 and tried to add an image. I get an "Invalid Security Token" error and the image isnt uploaded. I can upload the same image to 'old-style' H5p content in the same course, and to e.g. Moodle books, ATTO, etc
   
   
2. Platform and version number. E.g. Drupal, Wordpress, Moodle.
   Moodle 3.9
   
   
3. Mobile or Desktop
   Desktop
   

I am now developing own H5P component.. 

my Style issues have been resolved to some extent..

but big issue is still left... I want change library.. and customizing..

change location html template of component.. and language..

How to change and re-upload library?

Hello,

When I try to create new content using any content types I get "You Must Choose An H5P Content Type Or Upload An H5P File." error message. Does anyone encounter the same issues? I am stuck, please any kind of help or suggestion will be greatly appreciated. Please let me know what I am doing wrong here. I am trying to create content on Drupal 7.70, PHP 7.2.31

Thanks in advance.
