can not create index templates in cerebro 0.9.4 Pls help

[KlavsKlavsen]

error output from elasticsearch isn't shown - and the json IS valid - so its very hard to debug what it doesn't like about it. looking at cerebro log output - there isn't anything either. So this topic SHOULD be about, cerebro capturing output from its elasticsearch requests - and making them available to the user - when elasticsearch rejects/fails.

This issue seems to be bogus and should be closed. I can alter an existing template just fine, once I enter the correct data. I've created #530 about the issue cerebro has - that makes this hard.
