Checkout not working

Hi,
I am quite new to joomla and in the process of building an e-commerce site www.fonefixhoniton.co.uk i installed the JSN Teki Joomla 3 templat ealong with Hikashop on to my own pc to build a site to practice on and all went well.

I have since designed the same site live and all seemed to be going well, however if i attempt to go to the checkout when there are no products in the basket i get the usual message staing i have no products which of course is fine. When i add a product to the basket and attempt to go to the checkout i get this url www.fonefixhoniton.co.uk/iphone-repairs/iphone-4s/checkout when directing there from the product page which is a blank page !! if i attempt to just click the checkout button i again get a blank screen.

Any help would be greatly appreciated and i thank you in advance.

Hi, I have enabled debug mode and get this error when going in to the checkout after adding a product.

Fatal error: Allowed memory size of 25165824 bytes exhausted (tried to allocate 32 bytes) in /home/sites/fonefixhoniton.co.uk/public_html/libraries/joomla/database/driver/mysql.php on line 397

When i enable Devoloper mode for debugging level i get this error with a product in my cart:

Strict Standards: Only variables should be assigned by reference in /home/sites/fonefixhoniton.co.uk/public_html/plugins/system/canon/canon.php on line 25 Fatal error: Allowed memory size of 25165824 bytes exhausted (tried to allocate 84 bytes) in /home/sites/fonefixhoniton.co.uk/public_html/libraries/joomla/database/driver/mysql.php on line 397

When there is no product in the cart i get as in the attached screen shot.
