我的 Joomla 网站有问题。菜单项的 SEO 可以有效地工作。因此，如果我输入“www.example.com/about”之类的内容，它将起作用并显示相应的文章页面。所以这表明 SEF URL 和 apache mod_rewrite 设置是正确的。
我的问题是文章别名 SEO。
我添加了一篇名为“privacypolicy”的新文章，默认情况下，Joomla 为该文章创建了别名（privacy-policy）。然后我尝试打开这个页面（www.example.com/privacy-policy），但我得到了 404 page not found 错误。我曾尝试将这篇文章放在各个版块和类别中，并尝试使用完整路径访问 URL（例如：www.example.com/categoryname/articlename），但仍然出现 404 page not found 错误。
然后我尝试添加另一个虚拟文章来测试这个 SEF URL 功能，并发现 SEF URL 功能不适用于文章别名。它适用于菜单项别名（如果您将文章作为菜单项，例如文章/博客格式）。
我的问题是，我怎样才能访问文章（使用别名 URL），而不必将这篇文章作为博客放在菜单项中？我什至尝试使用一些 Joomla SEO 扩展，并希望这可以修复错误，但我仍然遇到同样的问题。我已将我的 htaccess.txt 更改为 .htaccess（我相信这可以使菜单项别名有效地工作）。
以下是我的 .htaccess 文件的内容：
