I’m having the same problem.
Yes, I do, but it always says 0. Today I tried unchecking the option to have spam deleted after a month, and now spam is showing up in the queue, so it looks like it’s been getting deleted immediately instead of after a month.
Or maybe I’m just being dumb and Akismet auto-deletes things it knows are definitely spam, so I shouldn’t worry about this?
I’ve cleared my cache and it doesn’t work. I’m at a loss. Not as pleasant to use WordPress when I have to log in 20 times a day.
