### 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.

If the identifier in the message is different, for example `name{figure.1.1}`, the problem is (usually) due to a problem of package interaction. Some packages are simply incompatible with hyperref, but most work simply by ignoring it. In most cases, therefore, you should load your package before you load hyperref, and hyperref will patch things up so that they work:

> `\``usepackage{your package}`
> ...
> `\``usepackage[opts]{hyperref}`

You should do this as a matter of course, unless the documentation of a package says you must load it after hyperref. (There aren’t many such packages: one such is memoir’s “hyperref fixup” package memhfixc.)

If loading your packages in the (seemingly) “correct” order doesn’t solve the problem, you need to seek further help.
