I'm running an e-commerce theme from someone who vanished without a trace and will no longer offer support. Unfortunately, my site now has even more bugs with the new WordPress update. At the top of the dashboard it says:
Warning: Missing argument 2 for wpdb::prepare(), called in .../wp-content/themes/TheJewelryShop/lib/engine/nws-admin-functions.php on line 2777 and defined in .../wp-includes/wp-db.php on line 990
I've been told that this error will prevent me from seeing new orders in the "manage orders" section of the dashboard, which is obviously a big problem. Is there an easy way to fix this, just until I can find a new theme/developer?
