Magento: 1.9.2 Unknown cipher in list: TLSv1

Recently i have faced the problem while integrating WordPress in Magento.

when i try to install FishPig WordPress Integration.

Its shows me an error -> [Unknown cipher in list: TLSv1]

Solution:

Navigate to downloader/lib/Mage/HTTP/Client/Curl.php .

And changed the code:

$this->curlOption(CURLOPT_SSL_CIPHER_LIST, 'TLSv1');

To:

if(isset($var)){
   $this->curlOption(CURLOPT_SSL_CIPHER_LIST, 'TLSv1');
}
