Image Sequencing

I seem to have an unusual issue in live where we cannot upload pictures and just see the throbber. In dev which is hosted locally on Drupal everything works fine, out live site is in AWS and also running Drupal.  I can't see anything in the logs and in dev toolbar it just starts to upload the file but never finishes it.  I've tried changing from private to public files etc but still no joy.  Any ideas anyone?

Any help would be much appreciated.

Hello!

I'm having problems uplading h5p files to our Moodle. There is an interactive video that i downloaded from the h5p webpage and i can upload it without a problem. But then, there is an Image Sequencing file that for some reason just does not want to upload. I tried it in my Moodle and our schools' one. I tired some tips from previous similar problems like deleting .vtt files (after opening it in zip under image folder and so on), but likewise it does not work.  Is there a way to correct this? The message i get is as follows in Message 1:

Hello,

It seems that Image Secuquencing -library gives users points f.ex 3/3 points but doesn't deliver these to moodle grade book / grader report like f.ex course presentation does.
