@onur-baran also the fav icon has to do with browser cache and memory etc, which is out of control of NodeBB. If you’ve determined it is part of NodeBB, report it.
Get a list of recent topics though the API
Is there a way to get a list of the 10 most recent topics via the forum API?
I know that you can get the 20 most recent posts with the
api/recentmethod, and the one most recent post for each category with the
api/categoriesmethod, but these will also include replies to posts.
How do I get a list of all topics, but only the first post of each topic?
If you go into the ACP and change the behaviour of teaser to "first", then the API will return data for the original post only.
