“Exclude Certain Dates” doesn’t work

I set “Exclude Certain Dates” to Sept. 1, 2, and 5, but a post went out on Sept. 1 anyway. After that, I just hit the button to disable auto post scheduler. I’ll re-enable it tomorrow.

This has happened before, and I did the same thing then — disable, then re-enable manually.

I may have been confused by the British style of dates (d-m-y) rather than the American style I’m used to. But I don’t think that’s the case; I checked the dates over several times.

I’m running Auto Post Scheduler 1.6.3
