Opencart 2.1.1 Menu Link Issue - opencart

Question

I am using OpenCart v 2.1.1.
In the admin area, the settings area indicates that the theme is set to Default.
On the server, I navigated to catalog -> view -> theme -> default -> template -> common
and opened up the header.tpl file for editing.
Inside the header.tpl file, I located line 115 which appears to be the last item
<li><?php echo $category['name']; ?></li>
Then on the next line I added in:
<li>Contact Us<li>
I Saved Changes, refreshed web page, and the Contact Us link does not appear in the blue menubar.
What have I done wrong..

Answer 1

you need to delete the cache of the template engine, else it won't update the cached template.

Answer 2

seems you add this line to the not correct place. you should add it before the last </ul> tag. this is 114 line in OC2.1 version.
<li>Contact Us<li>
</ul>
The last part of the header.tpl:
<?php if ($categories) { ?>
<div class="container">
<nav id="menu" class="navbar">
<div class="navbar-header"><span id="category" class="visible-xs"><?php echo $text_category; ?></span>
<button type="button" class="btn btn-navbar navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse"><i class="fa fa-bars"></i></button>
</div>
<div class="collapse navbar-collapse navbar-ex1-collapse">
<ul class="nav navbar-nav">
<?php foreach ($categories as $category) { ?>
<?php if ($category['children']) { ?>
<li class="dropdown"><?php echo $category['name']; ?>
<div class="dropdown-menu">
<div class="dropdown-inner">
<?php foreach (array_chunk($category['children'], ceil(count($category['children']) / $category['column'])) as $children) { ?>
<ul class="list-unstyled">
<?php foreach ($children as $child) { ?>
<li><?php echo $child['name']; ?></li>
<?php } ?>
</ul>
<?php } ?>
</div>
<?php echo $text_all; ?> <?php echo $category['name']; ?> </div>
</li>
<?php } else { ?>
<li><?php echo $category['name']; ?></li>
<?php } ?>
<?php } ?>
<li>Contact Us<li>
</ul>
</div>
</nav>
</div>
<?php } ?>
I have checked it works with default. Of course do not forget clear cache of your browser.
