KLOXO升级最新版本网站500错误的解决办法 由于KLOXO是linux为数不多的免费主机面板，所以相当多的朋友选择在VPS上安装此面板方便管理自己的网站，好VPS也在博客中做过一系列的安装和使用教程。最近，有不少朋友升级最新版本后反应一些问题，主要表现为网站无法打开了，在KLOXO后台使用apache的显示500，使用lighttpd的显示空白页。 出现上面的问题，是由KLOXO升级引起的问题，原因在于PHP5.2.17-13加入了对php-fpm的支持，升级后无法像之前版本那样直接调用php-cgi文件。下面，我们提供修复此问题方法。 登陆进kloxo，进入命令控制台，在输入框执行yum downgrade php php-cli php-common php-devel php-gd php-imap php-mbstring php-mcrypt php-mysql php-pdo php-xml –y执行命令后，在下面的大输入框会出现以下内容：Loaded plugins: fastestmirror, protectbaseRepository ‘vz-base’ is missing name in configuration, using idRepository ‘vz-updates’ is missing

另外，由于不少的朋友反映最新版的KLOXO存在各种不适应的状况，所以，好VPS建议您勿盲目升级，并在KLOXO后台设定关闭自动更新。
