Wpdb Prepare Error on Checkout Page

I get the following error on the bottom of the page after a customer completes there payments and checks out.

Warning: Missing argument 2 for wpdb::prepare(), called in/themes/wooshoplite/functions.php on line 58 and defined in /wp-includes/wp-db.php on line 992

I found some further information here: http://make.wordpress.org/core/2012/12/12/php-warning-missing-argument-2-for-wpdb-prepare/ and turned off displaying errors as it suggested but was wondering if there is anything I can do to fix the route cause.
