fatal error message on checkout page

[magento2471]

I am using magento 1.7.0.2 and this error message just comes up now when i click the checkout button:

public_html/app/code/core/Mage/Checkout/controllers/OnepageController.php on line 168

Any idea what i should do to fix it?

Hi,

There should be a little more to the error - can you check and copy the entire contents so we can see *what* its referring to on168.

I'm getting the same error:

Fatal error: Call to a member function getQuote() on a non-object in /public_html/app/code/core/Mage/Checkout/controllers/OnepageController.php on line 168

Did you ever resolve this?
