As in the subject. If there's no posts waiting to be moderate it shows "Moderate (1)".
It's probably because I have recently accepted one post and then just immediately jumped to other page without waiting enough time to proceed the query well through the database.
What can I do with that issue now?
Note: I've done almost all of database clean-up operations, only without refill event streams (it stops in the middle of process and doesn't go any further).
EDIT: The main problem is solved
How? I don't know, it dissolved on its own. One time I've accepted a single post and then the number of posts waiting for approval just fixed. However, the option of refill event streams on stats page still seems to doesn't work properly (it stops during the process) but that doesn't cause any visible problems.
