PHP分析错误:语法错误，PHP 5.5.9中出现意外的文件结尾

我有以下代码：

<?php if ($template['issue']['raw_state'] == 0 && ($helper->user_coordinator($template['issue']['id']) || isset($nparams['tid']))): ?>
    <a href="?id=<?php echo $this->id('cause_form', 'id', $template['issue']['id']) ?>">
        <?php echo $bezlang['add_cause'] ?>
    </a>
<? endif ?>

它在我的大多数服务器上都运行良好，但在其中一台服务器上我收到了一个错误：

PHP分析错误：语法错误，中出现意外的文件结尾/第19行的var/www/dokuwiki/lib/plugins/bez/tpl/issue_causes.php，

这个代码出了什么问题？

整个文件issue_cause.hp:

<?php include "issue_box.php" ?>
<div class="bds_block" id="bez_causes">
    <h1><?php echo $bezlang['causes'] ?> <span>(<?php echo count($template['causes']) ?>)</span></h1>
    <div class="bds_block_content">
        <?php foreach ($template['causes'] as $cause): ?>
            <?php include "cause.php" ?>
        <?php endforeach ?>
    </div>
    <?php if ($template['issue']['raw_state'] == 0 && ($helper->user_coordinator($template['issue']['id']) || isset($nparams['tid']))): ?>
        <a href="?id=<?php echo $this->id('cause_form', 'id', $template['issue']['id']) ?>">
            <?php echo $bezlang['add_cause'] ?>
        </a>
    <? endif ?>
</div>
<?php include "removal_confirm.php" ?>
