Hi Olly 🙂
I recently did a clean install of all the updated versions of gateways, extensions and Wppizza latest version. When I finished the settings and started to add a new dish, there was this error showing:
/wp-content/plugins/wppizza/classes/subpages/subpage.posts.php on line 182
Here is a screenshot: https://drive.google.com/open?id=0B7ntydnfE5PoZHdLV2tGbkFUbG8
Thanks
