Unable to locate lines

Having an error locating the code to replace in complete.php, almost as if a file mismatch

<center><a href="unlink" style="font-size:30px;" class="unlinkButton"><i class="fa fa-unlink" aria-hidden="true"></i> Unlink</a></center>

does not exist

index.php lines have been set from complete to complete.php

the host does have Rewrite activated aswell inside .htaccess\

Thank you for your patience!

It changed a bit but the premise is still there.

<?php if (isset($_SESSION['user_id'])) { echo "<li><a href='unlink'>Unlink</a>"; } ?> to <?php if (isset($_SESSION['user_id'])) { echo "<li><a href='unlink.php'>Unlink</a>"; } ?>

Got it fixed! Thanks again!
