Error on submission

When I submit a form, I get this string of stuff at the top of  the confirmation page.

array(16) { ["type"]=> string(12) "notification" ["html"]=> string(1) "1" ["replyTo"]=> string(0) "" ["from"]=> array(2) { [0]=> string(7) "default" [1]=> string(10) "Charlevoix" } ["to"]=> string(25) "travelbox@interlochen.org" ["useOld"]=> bool(false) ["subject"]=> string(57) "Thanksgiving Departure Departure Travel Plan Notification" ["body"]=> string(5588) "
