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.


  1. Upload the files to the /wp-content/plugins/ssh-sftp-updater-support directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress


Installation Instructions
  1. Upload the files to the /wp-content/plugins/ssh-sftp-updater-support directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress


Great plugin

This solved my problems with setting up proper SFTP update/installation.
Works perfectly, thank you!

No Longer Working Properly

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

It works without any config changes.

I recently upgraded my VPS. After that I was unable to update plugins using SSH2. I was getting this error : “Unable to locate WordPress Content directory (wp-content)”. This plugin fixed the problem. Just put the plugin files in the plugins folder, enabled the plugin from admin area. Everything started working!
