Hi @GTA_giri 

Please share the code from line 110-130 for the file (app/code/core/Mage/Payment/Helper/Data.php) shared in error, it's issue because of customised code.

    /**
     * Retrieve payment information block
     *
     * @param   Mage_Payment_Model_Info $info
     * @return  Mage_Core_Block_Template
     */
    public function getInfoBlock(Mage_Payment_Model_Info $info)
    {
        $blockType = $info->getMethodInstance()->getInfoBlockType();
        if ($this->getLayout()) {
            $block = $this->getLayout()->createBlock($blockType);
        }
        else {
            $className = Mage::getConfig()->getBlockClassName($blockType);
            $block = new $className;
        }
        $block->setInfo($info);
        return $block;
    }
