我在我的 Prestashop 网站上安装了 1.5 版的 PayPal 模块，之后如果我尝试联系我的网站，我会收到此错误：
Warning: require(/web/htdocs/www.safarino.it/home/modules/paypal/backward_compatibility/backward.php): failed to open stream: No such file or directory in /web/htdocs/www.safarino.it/home/modules/paypal/paypal.php on line 127 Warning: require(/web/htdocs/www.safarino.it/home/modules/paypal/backward_compatibility/backward.php): failed to open stream: No such file or directory in /web/htdocs/www.safarino.it/home/modules/paypal/paypal.php on line 127 Fatal error: require(): Failed opening required '/web/htdocs/www.safarino.it/home/modules/paypal/backward_compatibility/backward.php' (include_path='.:/php5.6/lib/php/') in /web/htdocs/www.safarino.it/home/modules/paypal/paypal.php on line 127
我怎样才能修复它们？我无法删除此模块，因为 Web 面板也已损坏
