My panel view looks so different! What's going on?!
The new Komments view is only available for Kirby 3.6+ if you use a version below that, you'll still the the old moderation view.
I enabled webmentions but nothing happens
Komments does not provide an endpoint for webmentions but it listens on a webmention hook. In order to receive webmentions, you have to install the IndieConnector plugin.
I don't see any comments marked as spam
By default comments detected as spam are rejected. If you want to moderate spam comments, disable the auto-delete-spam option. (see options)
