When trying to upload an EPUB to iBooks via iTunes Producer on the iTunes Store, if you encounter the following error:
ERROR ITMS-5107: “◯◯.epub: Fixed-layout books must supply a landmarks" at Book (MZItmspBookPackage)
Here’s what you need to do…
First, in the content.opf file, locate the line:
<item id="toc" properties="nav" href="nav.xhtml" media-type="application/xhtml+xml" />
Open the file specified in the nav, such as nav.xhtml or toc.xhtml.

Then, structure it as follows:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html >
<html xmlns:epub="http://www.idpf.org/2007/ops" lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Language Comic KATSUSHIKA HOKUSAI</title>
</head>
<body>
<nav epub:type="toc" id="toc">
<h1>contents</h1>
<ol>
<li>
<a href=“◯◯.xhtml”>◯◯</a>
</li>
</ol>
</nav>
<nav epub:type="landmarks">
<ol>
<li><a href=“◯◯.xhtml" epub:type="cover">◯◯</a></li>
<li><a href=“◯◯.xhtml" epub:type="bodymatter">◯◯</a></li>
