With this modifications it works for me:

STEP 1:

modules/TinyMCE/responsive_filemanager/filemanager/config/config.php

Line 9:

replace

mb_http_input('UTF-8');

with:

mb_http_input();

After doing that you will see the download files again instead of the empty pop
up. But trying to upload new files will give an error such as "saveImage: This
is not a resource". So go to step 2.

STEP 2:

modules/TinyMCE/responsive_filemanager/filemanager/include/php_image_magician.php

Line 2791:

replace:

if ( ! is_resource($this->imageResized))

with:

if ( ! is_resource($this->imageResized) && !($this->imageResized instanceof
\GdImage))
