Turn server http caching off

    Your error description and action are not very clear: “please contact your server administrator”

    In the virtual host for my site I have added:

    <Location "%docroot%">
   CacheDisable on
</Location>

    to the template and checked that this has loaded okay.

    But the error still shows 🙁

    What exactly is Apache doing that it shouldn’t be doing?

    How are you testing for http caching in your code?

    Any help appreciated

    Hi @dzseti,

    Thank you for your message.

    I test it by downloading the same image twice using the cURL function. The first time I send the headers is simulating a browser supporting WebP, and the second time simulating a browser that does not support WebP.

    The size of the downloaded images should be different – if it is the same, it means that the second query was based on the cache, and it should not be.

    Got it. That’s helpful. So I’ll have to keep digging. Could it be a WP plugin used for caching?

    Thanks for a swift response 🙂

    Yes @dzseti, but most often it is server-side cache. If you solve the problem, the error message will automatically disappear.

    If you find a solution, please inform me – maybe someone will have similar settings to yours and will be able to suggest what you did. I will be very grateful!

    In this case it was neither Apache nor the WP caching plugin that I use (WP Super Cache)

    It turned out to be cloudflare.com that I use for security reasons as much as for caching. Had to turn off caching by enabling Development Mode

    All working as it should. Many thanks 🙂

    Plugin may actually work without turning off caching at cloudflare.com, if you only use curl to test for caching and not for processing

    @dzseti, this is great information. For users, I think there would be a problem too. One user walks in from Chrome and loads images in WebP, and another uses a browser that does not support WebP and would also be forced to redirect to WebP.

    Could you describe step by step how you did it? If you can, add screens. I will be very grateful!
