Just change the oil filter again (leave engine oil in car)and clean the area up and re check for leaks. Its possible the filter has a small hair line crack or split in it. That would be what I'd do first. If you do change the oil filter make sure the rubber seal on the filter has some oil on it so the seal doesn't grab when you tighten it up.
