Download not working in Chrome
Using a local instance of H5P-Drupal 7.
Recently, users clicking the the download button in Chrome (v65, PC) for any object type see a gibberish display - it looks like the .zip (.h5p) file is being written to the screen instead of being offered for download. There was a similar posting last year by another user that shows the gibberish display: https://h5p.org/sites/default/files/Screen%20Shot%202017-03-10%20at%201.59.41%20PM.png
In Firefox the file downloads correctly. Chrome previously worked fine.
Any suggestions as to what is happening or ways to fix Chrome?
