Whoops! Sorry, but you are not allowed to perform the action requested.

Please look at the /includes/classes/shopping_cart.php file ON THE SERVER (ie: NOT on your PC)
What does line 180 say?
And lines 1243 and 1244?

Line 180

$this->cleanup();

Line 1243

break;

Line 1244

}

Also, you said that if someone starts with an empty cart, then adds something, then clicks to checkout, and logs in, that they get this "whoops" message; and you said that at that point their cart is *not* empty, right? Can you check what happens when they then log out again? If they just log back in right away, are all the same contents in their cart just as if they'd just added that item to the cart before getting the error message?

When somebody starts with an empty cart ans has NOT logged in and goes to check out, they will get a section asking to login but once logged in they get the whoops message BUT...

If you login and add items to an empty cart you can check out fine
