Error codes: rewrites_cached &#8211; nginx

Hi @realmoag,

Thank you for your message.

You’re using Cloudflare, right? Have you entered data for Cloudflare in the plugin settings, in the CDN Settings section?

Best,
Mateusz

Hello,

Thank you for your reply.

Yes I am using Cloudflare.

I can’t seem to find the section that you have mentioned, can you please elaborate and explain more?

Thanks in advance

@realmoag There are four tabs in the plugin settings panel. These tabs appear at the top of the plugin settings page: General Settings, Advanced Settings, CDN Settings, and Help Center.

Sorry for the confusion, I had an older version of the plugin and I have updated it and entered the global Cloudflare API key and the zone id and I am still getting this error.

Please, contact your hosting’s technical support or CDN’s support and send them the following message:I have a problem with the cache for HTTP requests on my website – https://sirodex.com. This prevents JPEG or PNG files from being dynamically redirected to WebP or AVIF, depending on whether the browser supports the format. Here are potential sources of this issue:
– the server or CDN server does not support the “Vary: Accept” HTTP header or handles it incorrectly (the cache for redirects should be based not only on the URL to the file, but also on the value of the Accept header sent by the browser)
– the server or CDN server does not support the “Cache-Control: private” HTTP header or handles it incorrectly (this header should be able to disable caching for static files on the CDN server or proxy server)
– the website is running on the Nginx server without support for .htaccess files and not all the steps described in the plugin FAQ (in the question: Configuration for Nginx) have been followed correctly

I have just bought a Cloudflare pro plan which If I am not mistaken allows me to use vary: accept header but still I couldn’t figure out how to fix the issue.

@realmoag Then the error is related to your Nginx configuration. It’s probably related to this bit of configuration:

location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {

        expires max;

        log_not_found off;

}

Please read question “Configuration for Nginx” in the plugin FAQ carefully. Pay special attention to step 4.

I did update the configuration before I have posted this and removed png,jpg,jpeg from the config but unfortunately its still giving the same error.
I suspect its Cloudflare issue because when I am using development mode in Cloudflare the error goes away but I want to know how to fix the settings for cloudflare.

here is the nginx config:
