Hi @seabl -- this just needs to be rebased over the latest master branch, as we've fixed the unrelated issue which is causing the tests to fail!

You can do that by following the process outlined here, but you may be able to skip step 2 if your master branch is still in sync with publiclab's master branch: https://publiclab.org/wiki/contributing-to-public-lab-software#Rewinding+the+master+branch

Thanks!
