@g0st Pushed an update so that the topic cards use the topic thumbnail if available, and added a few extra options in the widget config.
Feel free to open any other feature requests in the github issues.
Is there a way to completely remove a post once it's been purged or deleted by admin?
Hm, when a topic is purged, it should be gone from the database, so it sounds like the purging isn't completing.
Do you see any errors in the NodeBB log?
When I attempt to purge the topic, an error message 'Error This topic has already been deleted' appears.
The topic remains - http://pasteboard.co/1JHd886q.png
Sounds like it may be stuck in cache. I'd clear your cache and see if it goes away.
