  • The cause of this problem is that you are using PHP 7 and Magento 1 is not fully compatible. The solution can be found in the linked duplicate even if your error message is not mentioned there. – Fabian Schmengler Apr 5 '16 at 8:38

$out .= $this->getBlock($callback[0])->$callback[1]();


$out .= $this->getBlock($callback[0])->{$callback[1]}();
