When you are at a past events page, the sort order is backwards. I would expect December events, followed by November, October, and so on. However, it is showing with September events first on the list. Here’s an example of the expected behavior from your showcase: http://backtothetablecookingschool.com/classes/past/?action=tribe_list
So my question is how to reverse the sorting on these pages?
I have tried under the Twenty Thirteen theme and get the same results. I also downgraded to 2.0.x and it worked as I expected it to.
