我正在一个以前由其他人创建的网站上工作。每当我尝试使用插件（例如Dropbox Backup&Restore、Reset WP）时，都会出现http 500错误。[我使用filezilla进行了备份。]

using any plugin results in http 500 error (and only plugins)
故障排除
-htacces。bak（ftp）x
-PHP内存限制（ftp）x
-插件故障x
-文件夹权限（ftp）x
-损坏的核心文件（ftp）x
-主机端问题-contacted

I am at a loss here, and don\'t know what else to try. Now, it might be a fault on the hosting end, but I would really appreciate some input as to what else might be causing this.
