Error displayed on category pagees – can’t change the variation image by clicking on the small images

Williame Hoc

Hello,

On the category pages, I can’t change the variation image by clicking on the small images.
This problem appears after several hours and only when Wp Rocket is activated. As soon as I’m connected to WP Rocket and the cache is deactivated, this problem no longer occurs.
The same applies when I delete the cache.
At first, I thought it was an error loading the js. So I completely disabled this optimization. I also disabled lazy loading.
But no, it’s back.
I saw on the forum that this problem has already appeared with other users. But I haven’t seen any response.
What can I do?
Isn’t it possible to disable ajax loading on your side, as well as lazy loading?

The error :
https://micro-bikinis.fr/wp-json/woo-variation-swatches/v1/archive-product/23181?_locale=user – 403 error
https://micro-bikinis.fr/wp-admin/admin-ajax.php?action=rest-nonce – 400 error

Thank you

I have find something :
“The reason why your server is responding with “cookie nonce is invalid” is because the request that WordPress Popular Posts sends to it contains a nonce (security token basically) to confirm that the request is a genuine one, however this nonce is stored on the current page as a text string and if said nonce isn’t regenerated at least once per day then this happens: WPP will attempt to use said nonce, WordPress will find that it has expired (it’s default lifetime is one day(ish)) and then will reject the request, hence 403.
I know you said that you haven’t changed anything caching related in a long time but I recommend having another look at your site’s configuration (including page caching rules) as something must have changed that’s now causing this issue.”

For my part, I ask that the cache never be regenerated. So it’s never flushed. Simply because I have a very heavy multilingual configuration. So I need to have unlimited cache time unless I’m really modifying something on the site.

So it’s your plugin that generates this request with the nonce?
Isn’t it possible to modify it to get around this problem?
That would be very, very useful 😉

Thank you

Hi again,

In this files right ? :
woo-variation-swatches-proincludesclass-woo-variation-swatches-pro-rest-api.php
And
woo-variation-swatches-proincludesclass-woo-variation-swatches-pro-settings.php

Can you consider an option for unlimited cache? Really appreciate.

public function pre_serve_request($current, $response, $request, $server) {

$cache_api_response = wc_string_to_bool(  woo_variation_swatches_pro()->get_option( 'cache_api_response_in_browser') );

if ($request->get_method() === WP_REST_Server::READABLE && $cache_api_response) {

$route = $request->get_route();

if (str_starts_with($route, '/woo-variation-swatches/v1/archive-editor-preview')) {

return $current;

}

if (str_starts_with($route, '/woo-variation-swatches/v1')) {

$cache_api_max_age = absint(  woo_variation_swatches_pro()->get_option( 'cache_api_response_max_age') );

$date_format = 'D, d M Y H:i:s';

$expires     = MINUTE_IN_SECONDS * $cache_api_max_age;

$server->send_header( 'Expires', gmdate( $date_format, time() + $expires ) . ' GMT' );

$server->send_header( 'Cache-Control', 'public, max-age=' . $expires );

}

}

return $current;

Hi Williame,

Thanks for reaching out to us.

Nonce is a common practice in WordPress to avoid CSRF attacks.

So, the request should go to the Caching plugin support.

For example- Litespeed caching is already offering the ESI Nonce feature, to avoid this kind of caching error.

You can check this article- https://blog.litespeedtech.com/2020/07/08/cache-wordpress-nonces/ and send a feature request to your caching plugin.

Thank You
