Looks like your config file has a syntax error on line <?php echo $line_num; ?>.
Here is a snippet around that line
<br />
<br />
<div style="text-align: left; margin-left: 80px; margin-right: 80px; border: 1px solid black; padding: 10px;">
<tt>
<?php for( $i=$line_num-9; $i<$line_num+5; $i++ ) {

echo "<div style=\"color:red;background:#fdd\">";

continue;
echo "<b>" . ($i+1) . "</b>: " . htmlspecialchars($file[ $i ]) . "<br />";
if( $i+1 == $line_num )
echo "</div>";
}
?>
</tt>
</div>
<br />
Hint: Sometimes these errors are caused by lines <b>preceding</b> the line reported.
