Thread:Extension talk:DynamicPageList (Wikimedia)/Not showing new pages added to category/reply (2)

I am seeing the same issue on MW 1.23. It randomly says there are no listings, even if there were prior, when adding a category that would result in getting displayed.

As above, a null edit fixes the issue. What cache settings should I be looking at, on the MW end or browser (clearing browser cache does not help)
