The field name (case matters), that the form is on a page with the value, and that the page is published. See When a merge tag stays empty |

Only fields of groups for posts and Settings Pages are listed; the menu only shows for people who can edit forms |
| Choices from CAFE does not appear |
The field type: only Drop Down, Multi Select, Radio Buttons and Checkboxes |
| The form shows its own choices |
CAFE had no choices: a Collection without items. In the editor or Preview: the form is not placed on any page yet (needed for page Collections) |

Save the form and reload the editor |
| There is no CAFE item under Form Settings |

| The feed saved nothing |
The entry notes. They say which value was invalid, or that there was no user or post |
| "The form was not sent by a logged-in user" |
The feed saves to the user's profile; require login in the form's Restrictions |
| "This entry has no post" |
The feed saves to the Post fields' post, but the form has no Post fields; save to a new post instead |
| A field is missing in the feed list |
Only top-level fields of groups for posts and users are offered, of the types in How answers become CAFE values |
| "An uploaded file is not in the uploads folder" |
The upload path was moved (for example with the gform_upload_path filter) outside wp-content/uploads. Keep Gravity Forms uploads inside the uploads folder |
| "The file type of ... is not allowed" |
WordPress does not allow that file type, or the file's content does not match its extension |
| An image was not saved in an Image field |
The upload was not an image, or not one of the CAFE field's allowed types |
