It’s looking like there’s an issue with the ‘vote_history’ field:

StandardError: An error has occurred, this and all later migrations canceled:

There was another report of a similar error recently - Bootstrap failed with exit code 1 Though no solution posted there yet.

Perhaps this is a conflict with having previously installed the Pavilion plugin? @Hifihedgehog, did your site also previously have that installed too?
