Hi, I would really appreciate your help in fixing this error. I'm not a technical person for web development and this is why I have downloaded hummingbird because it seems it can help me with just a click of a button. I have downloaded your plugin as a trial atm so I hope it will be worth $50 a month for me to keep it running.

Anyhow the error I am getting is as follows:

Browser Caching is not working properly:- Your server may not have the "expires" module enabled (mod_expires for Apache, ngx_http_headers_module for NGINX)
- Another plugin may be interfering with the configuration
If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.

Please, can you advise or help as best as you can.

Kind regards,

  • Dimitris

    Hey there Terence,

    hope you're doing good and thanks for reaching us! :slight_smile:

    Browser caching is using this "expires" module which is different depending the server type, for example mod_expires for Apache, ngx_http_headers_module for NGINX.
    While on HummingBird -> Browser Caching you should be able to see what's your server type as HB locates that automatically. Then, you are prompted with some additional steps that have to be made. In the case of an Apache server, these can be made automatically as long as the .htaccess file of your installation is write-enabled, NGINX servers (like my screenshot) requires some server access and the settings should be made manually.

    On top of that though, the appropriate modules I mentioned before should be activated and working. In order to check that, please contact your hosting provider asking them that the appropriate module is up and running and that there're no overrides on their behalf.

    After that, you should double check that the appropriate steps described in HummingBird -> Browser Caching are in place, so you should check either .htaccess file if you're on an Apache server, or /etc/nginx/nginx.conf (or /usr/local/nginx/conf/nginx.conf) if you're on a NGINX server.
    If these checks are too much for you, feel free to ask your hosting provider support staff to check these too, it shouldn't be too much for them.

    About the Uptime monitor page, there's been some inconsistencies in our servers considering this.
    Could you please inform me if the Uptime service is working in your Hub page?

    Could you also grant us with support access to your website via our "WPMUDEV Dashboard" plugin in order to have a better look of your settings?
    More info on granting us access (and a how-to manual) can be found here

    I look forward for your feedback on this!
    Warm regards,

    Hi Terence,

    About the Uptime monitor, it looks like there was a temporary issue accessing your site as I was able to activate the monitor for you now.

    As for the browser caching, first thing to do is check that you have "expires" module enabled on your server, unfortunately this is not something we can do for you and you will need to get in touch with your server provider and ask them to enable "mod_expires" module for you.

    Let us know what they said and if the browser caching is working after you have it enabled.

    Best regards,

Thank NAME, for their help.

Let NAME know exactly why they deserved these points.

Gift a custom amount of points.
