Plug-in not working with latest WordPress Version

I noticed it too.
When I upload an image, I get a “HTTP Error”, which I have not when I disable the plugin.

Console says :
load-scripts.php?c=0&load[]=jquery-core,jquery-migrate,utils,plupload&ver=4.5.2:25 POST https://mysite.fr/wp-admin/async-upload.php 500 (Internal Server Error)

Using WP version 4.6.1, images are much larger in filesize than the originals!
Example: I uploaded a file that was 200k in filesize, after the upload it is 1M.

We run this plugin on many WP sites, please fix!

So is this not working anymore then??

is not working anymore

Working fine with 4.7.4

Working fine for me too with 4.7.5

But I can’t geto the “force re-compression of uploaded JPEG images” function work.
Did it ever work ?
