There is already an index in ES. I am using ElasticSearch-PHP as client.  
According to [ES docs](https://www.elastic.co/guide/en/elasticsearch/client/php-api/5.0/_index_management_operations.html) these code should change ES settings:

$params = [  
'index' =\> 'my\_index',  
'body' =\> [  
'settings' =\> [  
'number\_of\_replicas' =\> 0,  
'refresh\_interval' =\> -1  
]  
]  
];  
$response = $client-\>indices()-\>putSettings($params);

But after running code this error is shown:

**Fatal error** : Uncaught exception 'Elasticsearch\Common\Exceptions\Forbidden403Exception' with message '{"error":{"root\_cause":[{"type":"cluster\_block\_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster\_block\_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}

How can I solve it?  
Thank you in advance.
