[Solved] problem with router

The problem with the routing was solved

FlowRouter and Iron-Router are two different routers, have you installed both of them?? You should only have one.

Hellos, thanks for the reply. Sorry I mistaken, i installed kadira flow-router not iron

also, looking at the console I can see the following errors:
meteor.js?hash=27829e9…:930 Exception in defer callback: Error: Expected template or null, found: undefined
