让我们从基本的背景开始。我们最近将我们的网络托管带到了内部。很少有旧网站仍然使用 Perl。我没有使用 Perl 的经验。让我们开始。我们的主域上有一个这个子网站。

当您访问网站时,我们会收到以下错误消息
"Software error:
Can't call method "display" on an undefined value at /var/www/www.gatewayrehab.org/app/webroot/eap/index.cgi line 47."
查看 EAP 网站/目录,所有文件都在适当的许可下就位,我再次没有使用 Perl/Cgi 的经验。下面是 index.cgi 文件:
