Getting rid of 'Register' and 'Help' nav buttons

[Synergic]

Hello. I have an issue that has me completely stumped. I'm trying to remove the 'Register' and 'Help' buttons from the upper right-hand corner in nav bar (which appear when no user is logged in), but they just won't die. I removed the following code from users/includes/navigation.php:

<pre>

Code:

<li><a href="<?=$us_url_root?>users/join.php" class=""><i class="fa fa-plus-square"></i> Register</a></li>
                    <li class="dropdown"><a class="dropdown-toggle" href="#" data-toggle="dropdown"><i class="fa fa-life-ring"></i> Help <b class="caret"></b></a>
                        <ul class="dropdown-menu">
                            <li><a href="<?=$us_url_root?>users/forgot_password.php"><i class="fa fa-wrench"></i> Forgot Password</a></li>
                            <?php if ($email_act){ //Only display following menu item if activation is enabled ?>
                                <li><a href="<?=$us_url_root?>users/verify_resend.php"><i class="fa fa-exclamation-triangle"></i> Resend Activation Email</a></li>
                            <?php }?>
                        </ul>
                    </li>

</pre>


But the buttons remain in place, fully functional. I've tried grepping through the source and editing various different things, but the mighty buttons stand strong. Already tried flushing browser cache, and even tried using a completely different machine. A shove in the right direction would be highly appreciated!
