Also note that you're on a problematic Marathon version. I was thinking to upgrade from 0.23&0.10.1 to latest versions, but decided to wait after I saw an announcement on the marathon users list that 0.11 is not recommended for production from last week (Oct 9). I'm waiting until 0.11.1 is out... (hopefully soon?)
