You need to post more information for anyone to help you.

What have you tried?

What is the code at line 23 of global-imports.js?

Even though the issue is really old, I found it because I just had a very similar issue all of sudden in Meteor 2.0 and 2.1.

It all went away trying the same in a chrome incognito window. So I cleared all browser history and it all went back to normal.

I’ve also had issues with AdBlock and Meteor in the past (has to be disabled for localhost:3000)

No idea why this happens though.
