Neither your session save path in your server's php.ini not the installation/tmp directory is writeable. One of them must be writable for the installation to continue.

Please try giving the installation/tmp directory 0777 permissions with your FTP programme and reload this page. Alternatively, you can provide your FTP connection information below and ANGIE will try to do that for you, if your server allows it.

FTP Connection Information

The hostname of your FTP server without the ftp:// prefix, e.g.
The TCP port of your FTP server. Unless your host tells you otherwise, use 21
The FTP directory where your site's files are. If unsure, please remove its contents and press the Browse button next to it.
