+<h3>PDFTeX destination ... ignored</h3>
+<p/>The warning:
+<blockquote>
+<pre>
+! pdfTeX warning (ext4): destination with the same identifier
+(name{page.1}) has been already used, duplicate ignored
+</pre>
+
+</blockquote><p>
+arises because of duplicate page numbers in your document. The
+problem is usually soluble: see
+<a href="FAQ-pdfpagelabels.html">PDF page destinations</a> &mdash; which
+answer also describes the problem in more detail.
+<p/>If the identifier in the message is different, for example
+<code>name{figure.1.1}</code>, the problem is (usually) due to a problem of
+package interaction. Some packages are simply incompatible with
+<i>hyperref</i>, but most work simply by ignoring it. In most
+cases, therefore, you should load your package before you load
+<i>hyperref</i>, and <i>hyperref</i> will patch things up so
+that they work, so you can utilise your (patched) package <em>after</em>
+loading both:
+<blockquote>
+ <code>\</code><code>usepackage{<em>your package</em>}</code><br>
+ <code>...</code><br>
+ <code>\</code><code>usepackage[<em>opts</em>]{hyperref}</code><br>
+ <code>...</code><br>
+ &lt;<i>code that uses your package</i>&gt;
+</blockquote><p>
+For example:
+<blockquote>
+<pre>
+\usepackage{float} % defines \newfloat
+...
+\usepackage[...]{hyperref} % patches \newfloat
+...
+\newfloat{...}{...}{...}
+</pre>
+</blockquote><p>
+
+You should load packages in this order as a matter of course, unless
+the documentation of a package says you <em>must</em> load it after
+<i>hyperref</i>. (There aren&rsquo;t many packages that require to be
+loaded after hyperref: one such is <i>memoir</i>&rsquo;s
+&ldquo;<i>hyperref</i> fixup&rdquo; package <i>memhfixc</i>.)
+<p/>If loading your packages in the (seemingly) &ldquo;correct&rdquo; order doesn&rsquo;t
+solve the problem, you need to <a href="FAQ-gethelp.html">seek further help</a>.
