Whenever I change shipping

My site computacity.com/

Whenever i switched between shipping methods

or whenever i click proceed to checkout from the cart module
i get this error below

Fatal error: __clone method called on non-object in /home/content/c/o/m/comp7407/html/administrator/components/com_hikashop/classes/currency.php on line 1484

add the code:
if(is_object($ax))

before that line and it should solve the problem.

Thank you

It seemed be working now
hikahsop to the world!!
