Continuing the discussion from [Error 500 Internal Server Error](https://discuss.elastic.co/t/error-500-internal-server-error/46513):
I am getting 500 error after installing Graph into existing ELK stack with data. I keep getting:
Debug: internal, implementation, error
TypeError: Uncaught error: Cannot read property 'debug' of undefined

Can you supply the version numbers for Kibana, elasticsearch and the plugins?

Elasticsearch
Version: 2.3.1, Build: bd98092/2016-04-04T12:25:05Z, JVM: 1.8.0\_77
Kibana
4.4.2

You'll need Kibana 4.5
Going forward this version management gets easier as Kibana, elasticsearch and x-pack (the plugins) all get released with the same version number. Hence the leap to elasticsearch version 5.
