<?php endif; ?> 

<?php do_action('woocommerce_after_variations_form'); ?>

在此块你不关闭前一个两次打开一个PHP块。

<?php 
      /** 
      * woocommerce_before_single_variation Hook 
      */ 
      do_action('woocommerce_before_single_variation'); 

      <div class="single_variation clearfix"></div>  <<--THIS IS LINE 51 

     <div class="variations_button"> 
      <?php woocommerce_quantity_input
