### PDFTeX destination ... ignored

The warning:

>     ! pdfTeX warning (ext4): destination with the same identifier
>     (name{page.1}) has been already used, duplicate ignored

arises because of duplicate page numbers in your document. The problem is usually soluble: see PDF page destinations - which answer also describes the problem in more detail.
