"Results 1 to 19 of 25"
The way I see it, the forum is returning the 25 new/updated threads but only displaying 19 because you don't have permission to view the others. ('deleted' threads + staff board threads) So it returns them because they do exist, just hides them from you because you can't view them.
Or at least, that's my guess. I don't actually know for a fact if that's the issue. It could be something else entirely.
Does that make any sense? Probably not.
It's including hidden threads I can't see b/cos I dont have staff permissions?
