We’ve seen this before;
1) Confirm you DO NOT have any PDF Signature Fields or LiveCycle PDF Fields in your PDF Form.
2) Confirm you have at least one data entry entered into the Formidable Form.
If the above is confirmed, and you still do not see any fields, please send us a screenshot of the plugin’s entire “Export” tab page with the Formidable Form and Layout Selected, or complete this form for further assistance.
We remain at your service.
