I believe the image attached is self explanatory.  I linked several digital objects (PDFs), but they are not showing in the carrousel. What I am doing wrong?

When I click on "Edit digital object" and then "Or auto-generate a new representation from master image" in the field "Thumbnail representation", nothing happens (and when I go back to the same page the field is unclicked).

Hi Rogério, 

My first theory is that you might be running into the following issue, caused by a change in ImageMagick. Please see this thread for more information and a solution: 
Once you have this fix in place, you can try the derivatives regeneration task again to see if it resolves the issue. See: 
If that doesn't work, then I would next suggest that you make sure that all of AtoM's dependencies for digital objects are properly installed. See:
