Upgrading solved it. Thank you very much.
Is there any way to see how many posts were added in a specific date range?
We only show last day,week, month on the dashboard. I think we should allow a bit more flexibility to see any date range.
In the meantime this will give you the number of posts created between
db.sortedSetCount('posts:pid', min, max, callback);
maxwith a unix timestamp in milliseconds.
I mention that here, too: https://community.nodebb.org/topic/13972/
