Hi @filipenevola ,
Thanks, and sorry for being late - I just noticed your answer. The problem was occurring when trying to launch Meteor in development mode, making it crash with an error message saying something like ‘UI is undefined’.
I first forked iron:router locally and started by replacing
Template.registerHelper in a few lines, but since it didn’t seem to be sufficient I switched to FlowRouter.
I guess the new iron:router version wasn’t yet available on Atmosphere by the time I upgraded Meteor.
