Undefined JSite::getBody() after paypal redirect

Hi,
I am getting error on my website after payment.

Fatal error: Call to undefined method JSite::getBody() in /var/www/html/plugins/system/hikashopproductinsert/hikashopproductinsert.php on line 59

The error is on this line:

$search_space = substr($body,strpos($body,'<body'));

Hello,

Firstly, can you download the last Hikashop version through our website, install it and test it again ?
Also, if your not using the "Product insert in Joomla! articles" features, you should un-publish "HikaShop product tag translation plugin" and "
HikaShop product tag insertion plugin" plugins.

Thank you.

Hi Mohamed, Thanks for your reply.
I am using the 2.6.2 of hikashop. Does update will solve problem or still I have to disable those plugins
