Hello all. With the help from @julian there is a new version available that is compatible with v2.2.x.
@Andrea-0 try latest version of the plugin, v7. It should work now and be fully compatible with v2.2.x
This plugin adds a widget to your NodeBB forum that displays your FFXIV server status.
npm install nodebb-widget-ffxivarrstatus
After enabling the plugin within Extend > Plugins, go to Extend > Widgets, add it to a page, then select your server within the widget settings.
