To install the Ghost Kit plugin, go to Plugins → Add New in your WordPress admin and search for Ghost Kit. The plugin is free on wordpress.org and installs like any other WordPress plugin. Once it is active, an Effects panel appears in the block settings on every core block and every Ghost Kit block.
Requirements
Ghost Kit 3.8.0 and later needs WordPress 6.6 or newer and PHP 8.3 or newer. Ghost Kit Pro needs the same.
On PHP older than 8.3, WordPress does not offer the 3.8.0 update. The site keeps the version it runs, and the Plugins screen says the update needs a newer PHP version. Ask your host to switch the site to PHP 8.3 or newer, then update.
Install from the dashboard
- Go to Admin Menu → Plugins → Add New.
- Enter “Ghost Kit” as a keyword to find it in the list of available plugins. Click on the Install Now button.
