问题 使用Apache的重写模式：mod_rewrite 出错

请问：我在国外的liunx 虚拟主机 在joomla全局布置“使用Apache的重写模式：mod_rewrite ”为“是” 的时候只有主页打开其他页面提示Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, root@localhost 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.

Apache/2.2.3 (Red Hat) Server at www.touchina.org Port 80


我该改的都改了如.htaccess等，插件sef 也打开了，搜索引擎友好链接 为“是”网站显示 www.xxx.com/index.php/ 文章链接.html  如何去掉 index.php 和不打开：[glow=red,2,300]使用Apache的重写模式：mod_rewrite[/glow] 行吗

也许路径不对，你自己看看先。

那如何设置路径呢
