title: Searchkick: Elasticsearch not indexing "FORBIDDEN/12/index read-only"?
body: <p>I've setup a new development environment on my iMac and moved my rails app from a macbook air. It was working fine and indexing the data as well. Using the same version of gems. When indexing it gives following error.</p>
  
  <pre><code>Searchkick::ImportError: {"type"=&gt;"cluster_block_exception", "reason"=&gt;"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"} on item with id '74'
  </code></pre>
  
  <p>Is there any way I can solve this issue by modifying my elasticsearch.yml?</p>
