Oops. Looks like you've upgraded from an old version
No worries. Kibana has a new build system. Now its faster and lighter than ever before.

To fix this
Instead of cloning the entire kibana, you can grab the latest build here: http://download.elasticsearch.org/kibana/kibana/kibana-latest.zip

If you really want to run from source you can do so from the src/ folder. After upgrading you may need to clear your browsers cache to see all of the new features.
