Could be a cracked pan if tightened WAY too much, but try replacing washer (which always comes with the oil filter kits) and re-torquing bolt first.
+1. It's a crush washer and hound be replaced any time the. Bolt is removed. They may not have replaced it or may have over torqued it. Either way, start there. If you're fast & messy, it's a cheap fix (washer plus 1Q). If not, it's just the cost of the washer + oil charge, no biggie.
