The plugin’s functionality has completely vanished from my forum now. In the admin interface I see:
The forum posts in the category where users were previously able to rate topics show no ratings widgets anymore.
If I recall correctly, I had to choose a category to enable the ratings in the settings or use a special tag for the category. But I could find zero documentation for that in GitHub - paviliondev/discourse-ratings: A Discourse plugin that lets you use topics to rate things · GitHub and this thread is too huge to read through all posts for any hints.
Any idea what is wrong with my forum? It is up to date.
