Upload not working / Windows 10 - solution provided

[jf16]

The file upload ends in a fatal error: Fatal error: Uncaught ArgumentCountError: Too few arguments to function system_exec_cmd(), 1 passed in C:\xampp\htdocs\Filemanager\Jobs.php on line 990 and exactly 2 expected in C:\xampp\htdocs\Filemanager\Jobs.php:4780...

Solution: Add 2nd parameter $output in line 990 and line 983: if ($is_windows) system_exec_cmd('icacls "'.$file.'" /q /c /reset', $output);
