所以今天我收到了这个错误,我已经将其缩小到这个问题：

我的网站是我的音乐家页面here.它允许人们进来看我的照片,新闻,我的音乐和我正在玩的事件.

一切都在膨胀,我手动将数据输入MysqL,让它自动提供给主页.现在我正在添加控制面板,以便我可以从Web添加,编辑和删除数据库中的内容.

除了添加/编辑事件的能力之外,一切正常.我把它缩小到我无法输入2个URL或我收到此错误的事实.我需要输入2个网址(一个用于查看活动页面,一个用于购买门票)但我一次输入的数量不能超过1个,是否有任何我可以做的纠正或解决此错误,无论是在apache还是我的码？

编辑：

我正在添加完整的代码行,以便您可以确切地看到我正在使用的代码,

这是step 1的照片
