This plugin provides CKEditor 5 for editing messages and templates within phpList. It also integrates the El Finder file manager for file upload and selection.
The plugin is now included in phpList, so you should not normally need to install it yourself. You can upgrade to the latest version on the Manage Plugins page.
Install or upgrade on the Manage Plugins page (menu Config > Manage Plugins) using the package URL https://github.com/tatevikgr/phplist-plugin-ckeditor5/archive/master.zip
Click the Enable action button to enable the plugin. Note that only one editor can be enabled.
