Error when a logged in user try to create a comment
- As a logged in user,
- I go to a post,
- fill in a comment,
- I accept the Privacy Policy,
- press the 'post comment' button (or its translation),
- It takes me to a page where I get the error:
PHP Warning: Undefined array key "email" in... add_comment_meta( $comment_ID, 'wpcpc_private_policy_accepted', $_POST[ 'email' ], true );
