Yes, I ran a global search but found none. Nothing at all sets no-cache, on the server side.

Now, could it be a FF thing? In Chromium the response is

Status Code:200 (from disk cache)

for images, stylesheets, and scripts and

Status Code:200 (from memory cache)

for fonts.

If it is a browser issue, then what is causing it?

Great! I’ll re-try during the off-hours.

Not really resolved ??
Images still do not convert.

There is no Nginx.
I am on Apache 2.4.54 with PHP 7.4.30.

Also, when I hit Submit I now get:

Images queued for conversion. Progress can be seen in the Media Library.

And when I refresh API usage I see:

Image Service API usage: 	
Hourly requests: 	Unknown
Hourly limit: 	Unknown
Monthly requests: 	Unknown
Monthly limit: 	Unknown

I have another virtual host on which I hit Submit and nothing happens, whereas the usage is as follows:

Image Service API usage: 	
Hourly requests: 	25
Hourly limit: 	100
Monthly requests: 	25
Monthly limit: 	1000

Counts are not running up on either counts or usage.

When I submit individual images from Media it says Sending and then throws this:

Sending…

no-cache is not present in any configuration or .htaccess files. The main one is below:

I still have a dev copy of the site, and here it is:

Cache Contents

WP-Cache (0KB)

    0 Cached Pages
    0 Expired Pages

WP-Super-Cache (0KB)

    0 Cached Pages
    0 Expired Pages

The list is empty.

No browser caching occurs as well. For some reason I see Pragma: no-cache on requests in FF and Chrome.

Here’s a couple of fresh errors to show that the old syntax does not work in the current Apache:

[Tue Aug 02 07:25:41.916801 2022] [core:alert] [pid 3520:tid 692] [client 1.1.1.7:36658] C:/web/site/.htaccess: Invalid command 'order', perhaps misspelled or defined by a module not included in the server configuration, referer: https://www.domain.sfx/wp-admin/plugins.php

This is after allowing Jetpac hosts. The plugin added:

Allow from ...

and broke the site.

Suggestion: have the user choose old/new version of Apache before making changes to .htaccess because recovery is PAINFUL unless the plugin is deleted from disk.

Browser cache was enabled. I checked off the headers you suggested but am still getting 200 in the dev tools from repeated reloading of the shop page with product images. Should they not be 301 or 304, cant remember which?

I can see in the request headers “Cache-control:no-cache” and in the response header “cache-control:public” but I cannot see the “expires” header.

Also enabled HTTP compression but Lighthouse still recommends it:

I initially enabled deflate in Apache but got a WP note advising me against it and disabled it. What am I doing wrong?

Awesome, thanks a lot!

Are the links it’s reporting in the “Content” tab of WP Super Cache as being cached?

Dunno, I had to discontinue WP Super Cache for W3 Total Cache.

We cannot afford that effort and will have to pre-convert images to webp instead.

I can post it here as there is not much to it:

Looks like Memcached freezes soon after it starts and gets 1000-4000 hits/misses.

Actually, soon after the activation of memcache I started getting this error:

Fatal error: Maximum execution time of 30 seconds exceeded in C:\WWW\site\wp-content\object-cache.php on line 176
