zend studio打不开页面

今天想试一下zend studio, 在官方网下载好在win7下安装后，发现zend server其实就是apache, zend studio就是扩展了eclipse，但zend server/studio却还要收钱，真不知道是怎么遵守开源协议的。

创建一个test项目后，结果页面都打不开，返回的错误是这样的：Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, admin@example.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

花了不少时间看它们配置，发现配置都没什么问题，有点恼火啊，功夫不负有心人，原来这个文件Zend\ZendServer\etc\ZendEnablerConf.xml 第一行出现了乱码：锘??xml version=”1.0″ encoding=”UTF-8″?>
把它改为：<?xml 就行了
