+1 for me as well. I dit not explicitly install iron:middleware, but I was using iron:router, version 1.0.7. A simple meteor update iron:router updated a lot of iron packages for me:

iron:url               upgraded from 1.0.7 to 1.0.9

But the problem still existed. I had to explicitly meteor update iron:middleware-stack and with

iron:core              upgraded from 1.0.8 to 1.0.11
iron:middleware-stack  upgraded from 1.0.9 to 1.1.0
iron:url               upgraded from 1.0.9 to 1.0.11

the problem was solved.

Same problem with Chrome on my development and production server. Using Meteor 1.1.0.3. Fixed with a iron-middleware-stack update to 1.1.0. Thanks for the help. Wish I would have caught this sooner. Thought complaints of Chrome having a blank screen were just people on old phones. :frowning: Need to update to 1.3 soon.

I had faced the same error upon accessing http://localhost/admin after houston is installed to view mongodb collections.

When I ran meteor add houston:admin number of iron packages were updated including iron:middleware-stack to 1.0.11. This wasn’t good enough though.
