WordPress Toolkit is a feature-rich management interface that allows anyone to install, configure, and manage WordPress websites. WordPress Toolkit Lite is included FREE and WordPress Toolkit Deluxe is a paid upgrade with advanced features and smarter functionality. Availability of these tools may need to be enabled by your hosting provider.
WordPress Toolkit can be installed manually via the command line and adds a plugin in the cPanel, where you can install, update, delete WordPress installations, themes and plugins.
Login to the server via SSH as root, then run the following command:
sh <(curl https://wp-toolkit.plesk.com/cPanel/installer.sh || wget -O - https://wp-toolkit.plesk.com/cPanel/installer.sh)
That’s all. Once this is done, you can login to your cPanel, and you can see WordPress ToolKit was installed under “Applications” section.
