Hello Jeff K,
I'm using the latest version 2.1.12 of this plugin along with WP 3.6.1
But when i go to the custom fields page, i can see some of the fields created by default, also i can add some new field. But i cannot edit or delete the fields on there. I made some mistake when creating some field, and i want to delete the field, but i can find any button to delete the fields. How can i manage this? Thanks!
