If i look the statistics about posts monthly there are count all posts in the forum or only posts from sections what increase the post counter from members?
I have some sections where posts are not counted for members.
I have also a different at the statistic at front end.
The post count there is less than the actual in DB.
The Admin CP statistics will include all visible posts, even those that aren't counted.
The board totals statistics come from the collective sum of the discussion count on each node, and therefore does take into consideration those forums where the post counter is not increased and whether a post is visible or not. This accounts for the difference between the board totals statistics and what is in the database.
