wordpress中download monitor只可以列出来文件只可下载第一个

[qq_33782383]

wordpress 中download monitor插件中content-download version-list.php
下载列表可显示，但是除了第一个文件可下载，其他都是找不到下载

<?php
/**
 * List of versions
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit;
} // Exit if accessed directly

/** @var DLM_Download $dlm_download */

$versions = $dlm_download->get_versions();

if ( $versions ) : ?>
	<ul class="download-versions" style="text-align: center;">
		<?php
		/** @var DLM_Download_Version $version */
		foreach ( $versions as $version ) {

		    // set loop version as current version
			$dlm_download->set_version( $version );
			?>
			<li><a class="download-link;download-link filetype-icon <?php echo 'filetype-' . $dlm_download->get_version()->get_filetype(); ?>"
			       title="<?php printf( _n( 'Downloaded 1 time', 'Downloaded %d times', $dlm_download->get_download_count(), 'download-monitor' ), $dlm_download->get_download_count() ) ?>"
			       href="<?php $dlm_download->the_download_link(); ?>" rel="nofollow">
					<?php echo $version->get_filetype(); ?><?php echo $version->get_filename(); ?>
				</a></li>
		<?php
		}
		?>
	</ul>
<?php endif; ?>
