uploadify http error 500错误怎么解决

最近在.net下用uploadify上传文件，在普通页面下执行正常，后来发现在showmodeldialog窗口中不能正常上传，纠结了很久发现把jquery.uploadify.v2.1.4.js文件下的68行改成data.pagepath = "";竟然没事了。在普通页面还是showmodeldialog页面中都能正常工作。我以为万事大吉，那天把系统传到服务器上面的，悲剧了，报http error错误，看到那个红色的警告我傻眼了，后来加了onError方法，把info alert出来发现是<em>500错误</em>。我又恢复了jquery.uploadify.v2.1.4.js，还是不行，甚至把script参数传了http://**.**.**/...aaa.asmx/upload还是不行！我用的是webservice，没有用ashx作为后台处理文件。本地正常为什么放到服务器上面就不行了呢？我于是在后台加try catch,发现根本就不执行后台脚本！怀疑是文件夹权限问题，我也加了权限，甚至把写文件的代码都注释掉，直接reruen "1";仍然不行！我试着将script改成一个根本就不存在的路径，它报404错误，看来路径是找到的（要不然<em>怎么</em>报<em>500错误</em>呢），哎，以上各个改动我都一一之间组合尝试了，一个都不行，甚至我不放到服务器上面，就我本机，别人用电脑访问我的页面，页面可以访问，但是上传文件就是http error！各位大侠，谁能告诉我这到底是<em>怎么</em>回事呢？
