今天安装6.0的测试版，在godaddy的Linux服务器上，可是访问安装文件时（index.php) 显示如下：

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator and inform them of the time the error occurred, and the actions you performed just before this error.

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

后来把 .htaccess 文件禁用了（改成.old后缀），就可以打开安装页了。可是到了第三部就成了白页，无任何反应。

后来换了 5.3，也是上述情况。

期盼大神指点。
