WordPress won’t remember FTP password

Edit the file wp-config.php found in the root of your WordPress install and add the following three lines

define('FTP_HOST', 'ftp_host');
define('FTP_USER', 'ftp_username');
define('FTP_PASS', 'ftp_password');

Replace ftp_host, ftp_username and ftp_password with your own details.
