if you add the correct safe path as absolute path, there is no error message
Concerning the safe path:
It's sometimes a little bit difficult to find out what your server requires.
In order to get a hint, you can search for "upload_tmp_dir" in your Joomla system information.
In my case it says something like /var/www/web00/phptmp/
In this case /var/www/web00 would be the server path to your root directory. So if you have a folder "files", which you want to use for the safe path, the VM2 safe path would be /var/www/web00/files/
