Here’s the fix itself for the term names:

if ( ! function_exists( 'mh_qtx_force_current_language_term_name' ) ) {

    function mh_qtx_get_current_qtranslate_language() {
        global $q_config;

        if ( isset( $q_config['language'] ) && is_string( $q_config['language'] ) && $q_config['language'] !== '' ) {
            return $q_config['language'];
        }

        return '';
    }

    function mh_qtx_get_translated_term_name_from_i18n_config( $term, $lang ) {
        if ( ! is_object( $term ) || ! $lang ) {
            return null;
        }

        if ( ! isset( $term->i18n_config ) ) {
            return null;
        }

        $config = $term->i18n_config;

        if ( is_object( $config ) ) {
            $config = json_decode(
                wp_json_encode( $config, JSON_UNESCAPED_UNICODE | JSON_PARTIAL_OUTPUT_ON_ERROR ),
                true
            );
        }

        if ( ! is_array( $config ) ) {
            return null;
        }

        // Structure
        if (
            isset( $config['name']['ts'][ $lang ] ) &&
            is_string( $config['name']['ts'][ $lang ] ) &&
            $config['name']['ts'][ $lang ] !== ''
        ) {
            return $config['name']['ts'][ $lang ];
        }

        // Fallback variants for other possible qTranslate-XT structures.
        if (

        if (

            is_string( $config['name'][ $lang ] ) &&
            $config['name'][ $lang ] !== ''
        ) {
            return $config['name'][ $lang ];
        }

        return null;
    }

    function mh_qtx_force_current_language_term_name( $term ) {
        if ( ! $term instanceof WP_Term ) {
            return $term;
        }

        $lang = mh_qtx_get_current_qtranslate_language();

        if ( null === $translated_name ) {
            return $term;
        }

        /*
         * Clone the term to avoid mutating a shared cached object reference directly.
         */
        $term = clone $term;
        $term->name = $translated_name;

        return $term;
    }

    function mh_qtx_force_current_language_terms_list( $terms ) {
        if ( is_wp_error( $terms ) || empty( $terms ) ) {
            return $terms;
        }

        if ( ! is_array( $terms ) ) {
            return $terms;

}

Done, thanks, I will mark this topic as resolved.

I’m marking this topic as resolved, since its the problem of the qTranslate-XT plugin.

If someone’s need a fix – just comment assert() function on the line 102 in qtranslate_core.php. This check doesn’t need in production only for debugging.

PS: The problem was existed in PHP 7.4 too, but everything was worked just because PHP 7.4 and lower versions throws warning message in case of failure, and PHP8+ throws exception. Explanation of how assert() function work in PHP8+ https://php.watch/versions/8.0/assert-throws

Hey Mikhail,

I’ve tried to disable my own ‘jquery-3-6-0.min.js’ and get same error, but this time it’s default wordpress ‘jquery.min.js’ file.

Here, you can test on this website (search form at very top): https://antik.ua

When you open website everything’s ok, jquery is working, but when you start to type something in search form, then in console log browser gives this error:

POST https://antik.ua/?wc-ajax=aws_action 500 jquery-3-6-0.min.js:2

And for default wordpress jquery same error but with different name of jquery file.

POST https://antik.ua/?wc-ajax=aws_action 500 jquery.min.js:2

Both files are exist on hosting:

https://antik.ua/wp-content/themes/antik/js/jquery-3-6-0.min.js:2

https://antik.ua/wp-includes/js/jquery/jquery.min.js

Current PHP version is 8.2.1.

Hey Mark,

I have tried everything – cleared cache in product filter plugin, cleared cache in multicurrency plugin, recount prices, refreshed the lookup tables. Anything doesn’t help.

Here’s what I have also noticed, that when I’m set for example lowest price in filter, for example “17860” ukrainian hryvnas – after ajax call the link in browser adds parameter “?min_price=17860” and because the default currency is euro, filter is trying to search products that starts not with 17860 hryvnas price, but with 17860 euros.

And if I manually change the value in link to “?min_price=425” it shows me products that starts with price of 17860 hryvnas, based on currency rate 1 euro for 42 hryvnas.

So maybe the problem is that product filter plugin doesn’t convert input price in right currency and just uses default, despite that default currency doesn’t uses in fron-end?

Great, thank you very much!

Meanwhile I’ll try to use cron jobs.
