Question

曾经试图摆脱GTmatrix中的“添加过期标头”，但没有成功。我已经安装了WP Fastest Cache插件，并尝试了.htaccess的许多其他变体，这些变体是我在stackoverflow和人们有类似问题的其他网站上发现的，但没有成功-GTmatrix仍然显示相同的错误。

这是我当前的.htaccess：

Answer 1

请检查服务器主配置文件中的mod_expires模块已启用

您可以与托管服务提供商联系，或者如果您有权访问httpd.conf文件，则以下行应取消注释，以便使标头失效：

LoadModule expires_module modules/mod_expires.so

或者它可能会导致与您的插件相关的问题。您可以尝试使用这种轻量级的plugin for adding expires headers.进行检查，它可能无法满足您的全部目的，但有助于您确定插件能否正常工作。

Answer 2

我通过以下步骤解决了这个问题：首先检查我的apache站点配置，并确保AllowOverride都如下所示。

<Directory /var/www/mysite>
    AllowOverride all
</Directory>

然后尝试了以下命令：

sudo a2enmod rewrite
sudo a2enmod headers 
sudo a2enmod expires
sudo service apache2 restart

无法在WordPress中添加Expires标头
