SSH SFTP Updater Support


Keeping your WordPress install up-to-date and installing plugins in a hassle-free manner is not so easy if your server uses SFTP. “SSH SFTP Updater Support” for WordPress uses phpseclib to remedy this deficiency.

To use it, after installing and activating the plugins, add the necessary constants early in the code in your wp-config.php:

a) define('FS_METHOD', 'ssh2');

b) Others as detailed in the official WP codex

Just what I needed to update my Wordpress plugins on Linode. On Dreamhost it happens automatically, but I can’t run a socket server there.

Attempting to update from Wordpress 4.9.4 to 4.9.5, when I click on the update instead of giving me the screen from this plugin to enter the ssh details it goes straight to attempting to download from the Wordpress site and fails. I can still update plugins in 4.9.4 using this plugin successfully. Tried on two different sites. It looks like something in Wordpress 4.9.4 broke the compatibility with this and it was only revealed when attempting to use it to upgrade to 4.9.5
