discuz 论坛将www域名换成bbs后编辑器内swfuplaod上传报500错误，但是有时候能正常上传;
目前基本排除服务器上php的问题，因为改成空白页面也一样报错。
有人遇到过这个问题吗？求指点

回复讨论(解决方案) http status: 500 就是服务器上php造成的，出现了严重错误
可能是你上传的文件大小超过了 php.ini 中的限制
和文件大小没关系的，传多大的都一样；这个问题是在换成子域名后出现的，估计和flash跨域有关系
估计有什么用？何况还是乱估计！
http status: 500 是服务器发出的，可见请求已经到达了服务器
既然已经到达了服务器，那么就与域名无关了
之所以说估计是因为之前另一个站换域名也出现这个问题，并不是乱估计
500谁都知道是服务器内部错误，但是这个错是flash爆出来的，所以猜测flash内部出错
而且删掉那个php文件了还是报500，合理吗
删掉php文件报500可以
用firebug查看访问信息
swf里面放的 flash文件不支持跨域
已解决了，就是flash跨域的问题
删掉php文件报500可以
用firebug查看访问信息
用firebug 看不了flash内部的请求的
