How many blocks are shown at the "Show payout details" page?
All blocks that are valid for not paid payouts, the next block at the bottom would been green again since it reached the treshold but as it got paid already (if everything is correct) is not relevant anymore
I might remove the full list since it's cachefile is ~1 mb big for "old miners" growing fast, my cache folder contains 596 files, 75 mb total.
But site generation itself is so much faster with the database backend, i could turn off caching for sumary but since i only query your server every 10 mins, no point in generating it more often
i also removed around 300 mb of block and payout data i was parsing at the end
