index.php访问时是空缺
index.php访问时是空白
index.php访问时是空白,什么都不显示,上个月还可正常访问,给用户完全控制权限也不管用。
------解决方案--------------------
查看HTTP状态码。500,403,404还是502.
------解决方案--------------------
这个时候输出php错误信息才是王道
------解决方案--------------------
丢掉IE浏览器,果断上手chrome,在开发者工具的Network选项卡中,看看该请求的返回状态码。
------解决方案--------------------
200但未输出任何东西,即有以下可能:
你的程序文件没有输出动作。
或者出现一些逻辑上的错误,PHP程序主动退出。
建议可以修改一下程序文件,在代码最前和最后加入 echo "++++++\n".microtime(true); 看看有无变化
------解决方案--------------------
程序出致命错直接退了吧, 线上都关闭错误报告了.
------解决方案--------------------
你所说的index.php 是否有链接数据库的行为?
如果有,就先不要链接数据库,随便echo个什么东东试试,如果也不能输出,应该是编码的问题。
如果可以输出,估计是数据库或者核心文件或者配置文件出了问题
------解决方案--------------------
你的index.php页面是写的什么东西,难道是前端控制器。
