Kadira's Total Sessions chart is empty

We’re hosting our own kadira, and the issue we have since a few months, is that our Total Sessions chart is completely empty at all times.

I’m not sure how kadira does session tracking, but we must’ve broken something. Does someone have any insights into this?

Which version of Meteor are you running? At 1.8.1 Kadira stops working unless you manually update your meteorx package.

Ha, I didn’t know that. We’re using @lamhieu’s meteorx, is that not enough?
