Hi Chen

Thank you for reaching out.

Could you please provide a bit more detail so we can help you properly:

1. What exactly do you mean by "this switch" — are you switching between currencies using FOX, or something else?
2. Please share the URL of your shop page where the issue occurs.
3. What theme are you using?
4. What caching plugin are you using if any (WP Rocket, LiteSpeed, W3 Total Cache etc.)?
5. What version of FOX are you currently running?

Looking forward to your reply.

Thank you very much for your reply. My website is jinxellara.com, and I am using WooCommerce. When I click on sorting options—such as "Sort by popularity"—on the Shop page, the currency display keeps spinning and fails to load.

Hello Chen

Thank you for the details. When the page first loads, FOX detects the price placeholders and replaces them with real prices via AJAX — that works fine. But when WooCommerce reloads the product list after a sorting change, it injects fresh price placeholders into the page and FOX does not know about them, so they stay as spinners forever. If to refresh page all is fine: jinxellara.com/shop/?currency=GBP&orderby=popularity

The fix is to add a small script that polls for unresolved price placeholders and triggers FOX to process them. Add this to your theme's functions.php:

add_action('wp_footer', function () {
    if (!is_shop() AND !is_product_category()) {
        return;
    }
    ?>
    <script>
    jQuery(function ($) {
        var woocs_initial_load_done = false;

        document.addEventListener('after_woocs_get_products_price_html', function () {
            woocs_initial_load_done = true;
        });

        setInterval(function () {
            if (!woocs_initial_load_done) {
                return;
            }
            if (typeof woocs_shop_is_cached === 'undefined' || !woocs_shop_is_cached) {
                return;
            }

            var $loaders = $('.woocs_price_code.woocs_preloader_ajax');
            if (!$loaders.length) {
                return;
            }

            var products_ids = {};
            var products_currency = {};

            $loaders.each(function () {
                products_ids[$(this).data('redraw-id')] = $(this).data('product-id');
                if ($(this).data('currency')) {
                    products_currency[$(this).data('redraw-id')] = $(this).data('currency');
                }
            });

            $.post(woocs_ajaxurl, {
                action: 'woocs_get_products_price_html',
                products_ids: products_ids,
                products_currency: products_currency,
                current_currency: woocs_current_currency['name']
            }, function (data) {
                data = JSON.parse(data);
                if (!$.isEmptyObject(data)) {
                    $('.woocs_price_code').each(function () {
                        if (typeof data.ids[$(this).data('redraw-id')] !== 'undefined') {
                            $(this).replaceWith(data.ids[$(this).data('redraw-id')]);
                        }
                    });
                    $('.woocs_price_code').removeClass('woocs_preloader_ajax');
                    if (typeof data.currency_data !== 'undefined') {
                        woocs_current_currency = data.currency_data;
                    }
                }
            });
        }, 800);
    });
    </script>
    <?php
});

The key point: the interval checks first whether there are any price placeholders waiting to be resolved. If there are none, it does nothing and makes no server requests. It only fires an AJAX call when unresolved placeholders are actually present on the page, which happens right after WooCommerce reloads the product list via sorting.

Please test it ...
