At the end of the video, I refreshed but background images disappeared and all nav links are styled with the underline instead of one

look for if statements place like

//true
<li class="books <?php if($section== books){ echo " on"; ?>"...
<li class="movies<?php if($section== movies){ echo " on"; ?>"...

//false
<li class="books "<?php if($section== books){ echo " on"; ?>...
<li class="movies" <?php if($section== books){ echo " on"; ?>...

ah make a syntax correction!

This is the snippet of code from header.php.

<li class="books<?php if($section == "books") { echo " on"; } ?>"><a href="catalog.php?cat=books">Books</a></li>
                <li class="movies<?php if($section == "movies") { echo " on"; } ?>"><a href="catalog.php?cat=movies">Movies</a></li>
                <li class="music<?php if($section == "music") { echo " on"; } ?>"><a href="catalog.php?cat=music">Music</a></li>
                <li class="suggest<?php if($section == "suggest") { echo " on"; } ?>"><a href="suggest.php">Suggest</a></li>

Please make sure you have declared each section as a variable $section also make sure there is no space in between i.e. if(...

Actually, I don't think the space between if and brackets matters; it's a personal style choice: http://stackoverflow.com/questions/7691124/should-there-be-a-space-between-if-and-parentheses

I only have the possibility of clicking on suggest page. The rest says error code 500 and doesnt show.

I had the same problem, and I solved it. Here is the correct code:

<li class="books <?php if ($section == "books") {echo "on";} ?>">

Make sure you have quotation marks at correct positions. Missing or unnecessary quotation marks can generate wrong class names for your menu text, thus make your browser fail to pick up the correct CSS style (since you generated the wrong class name!)
