Warning Message on Woocommerce install

I get the following error message since installing WooCommerce on my shop page – http://infinitegrace.com.au/shop/

Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘WC_Query’ does not have a method ‘price_filter’ in /home/infin659/public_html/wp-includes/plugin.php on line 235

I tried updating the out of date template files but it didn’t fix the issue.

My system status report is below.
