I'm going with a drain plug issue as well. From the little we can see in pics, it doesn't look to be coming from anything up high, and it looks like the color and consistency of engine oil.
Like @Sandroad posted it could be an O-ring issue too. It's common-ish for the large O-ring for the filter housing to get set in the bottom thread rather than in the proper O-ring groove.
