第97行代码

<span class="iconb-date"><?php _e('Uploaded on:', MYAPB_THEMENAME); ?> <strong><?php echo get_the_date('d'); ?> <?php echo get_the_date('M'); ?> , <?php echo get_the_date('Y'); ?></strong></span> <span class="iconb-user"><?php _e('Uploader:', MYAPB_THEMENAME); ?> <a href="<?php echo get_author_posts_url($post->post_author); ?>"><?php the_author_meta('display_name',$post->post_author); ?></a></span> <span class="iconb-cate"><?php _e('Categories:', MYAPB_THEMENAME); ?> <?php echo get_the_category_list(', '); ?></span> <span class="iconb-comt"><?php printf( _n( 'Comments: <strong>%2$s</strong>', 'Comments: <strong>%1$s</strong>', get_comments_number(), MYAPB_THEMENAME),number_format_i18n( get_comments_number() )); ?></span> <?php echo get_the_tag_list('<span class="iconb-tags">'.__('Tags:', MYAPB_THEMENAME).' ', ', ','</span>'); ?>

其中显示评论及其条数的代码

<?php printf( _n( 'Comments: <strong>%2$s</strong>', 'Comments: <strong>%1$s</strong>', get_comments_number(), MYAPB_THEMENAME),number_format_i18n( get_comments_number() )); ?>

不是太懂，稍微查了一下，“如果 % 符号多于 arg 参数，则您必须使用占位符。占位符被插入 % 符号之后，由数字和 "\$" 组成。”

其中的"%1$s"和"%2$s"说占位符吧，少了\；说不是占位符吧，多了数字和$;搞不懂这里_n是做什么用的，也是一个函数，而且要四个参数？

<?php echo MYAPB_THEMENAME ?>的结果是arcadexls

<?php echo get_comments_number() ?>的结果是1

<?php echo _n( 'Comments: <strong>%2$s</strong>', 'Comments: <strong>%1$s</strong>', get_comments_number(), MYAPB_THEMENAME) ?>的结果是Comments: %2$s

<?php echo number_format_i18n( get_comments_number() ) ?>的结果是1

故最后printf()方法的实际调用为printf("%2$s", 1);　　很明显这个应该是有问题的

将代码中的1$和2$都去掉，改为

<?php printf( _n( 'Comments: <strong>%s</strong>', 'Comments: <strong>%s</strong>', get_comments_number(), MYAPB_THEMENAME),number_format_i18n( get_comments_number() )); ?>

OK，至少可以解决眼下问题，虽然没完全弄明白！
