Getting Iron:Router error when updating meteor from to

After updating Meteor and upgrading all packages ‘meteor update --all-packages’ and installing npm babel runtime, I’m getting an Iron:Router message in the browser when trying to run the project. I usually get this when there’s a routing issue. Stuck.

Looks like it was a problem with the Materialize package. It upgraded the package to 0.97.8 but the console was giving me several errors with Materialize. Downgraded back to 0.97.7.
