really i can't find
Although the steps to follow me in a sound and adjust the permision

[PrestaShopDeveloper]

1. "Allowed to create new files and folders" checks if the following functions "exist": 'fopen', 'fclose', 'fread', 'fwrite', 'rename', 'file_exists', 'unlink', 'rmdir', 'mkdir', 'getcwd', 'chdir', 'chmod'

2. "Allow to open external URLs" do not depends on the folder permissions. See below about the "allow_url_fopen"
http://php.net/manual/en/filesystem.configuration.php

Both require the function "fopen" to be allowed. So probably this is the problem here.
