Then try to search one more time and after check your debug.log file for any errors inside it. * Regards * Thread Starter [Oleg Komarovskyi](https://wordpress.org/support/users/komarovski/) * (@komarovski) * [3 years, 4 months ago](https://wordpress.org/support/topic/ajax-doesnt-work-under-php8/#post-16451022) * Hey Mikhail, this is what I get in log: * ```wp-block-code 2023-02-08T08:26:50+00:00 CRITICAL Uncaught AssertionError: detected in parse_language_info - cancelled by can_redirect, url_info={ "cookie_lang_front": "ru", "cookie_front_or_admin_found": true, "scheme": "https", "host": "antik.ua", "path": "\/", "query": "wc-ajax=aws_action", "path-base": "", "doing_front_end": true, "wp-path": "\/", "language": "ru", "doredirect": "detected in parse_language_info - cancelled by can_redirect", "set_cookie": true } in /home/antikua/antik.ua/www/wp-content/plugins/qtranslate-xt/qtranslate_core.php:102 Stack trace: 0 /home/antikua/antik.ua/www/wp-content/plugins/qtranslate-xt/qtranslate_core.php(102): assert(false, 'detected in par…') 1 /home/antikua/antik.ua/www/wp-includes/class-wp-hook.php(308): qtranxf_init_language('') 2 /home/antikua/antik.ua/www/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) 3 /home/antikua/antik.ua/www/wp-includes/plugin.php(517): WP_Hook->do_action(Array) 4 /home/antikua/antik.ua/www/wp-settings.php(480): do_action('plugins_loaded') 5 /home/antikua/antik.ua/www/wp-config.php(100): require_once('/home/antikua/a…') 6 /home/antikua/antik.ua/www/wp-load.php(50): require_once('/home/antikua/a…') 7 /home/antikua/antik.ua/www/wp-blog-header.php(13): require_once('/home/antikua/a…') 8 /home/antikua/antik.ua/www/index.php(17): require('/home/antikua/a…') 9 {main} thrown in /home/antikua/antik.ua/www/wp-content/plugins/qtranslate-xt/qtranslate_core.php on line 102 ``` * Looks like multilanguage plugin qTranslateXT produce this error ([https://github.com/qtranslate/qtranslate-xt](https://github.com/qtranslate/qtranslate-xt)). * Plugin Author [ILLID](https://wordpress.org/support/users/mihail-barinov/) * (@mihail-barinov) * [3 years, 4 months ago](https://wordpress.org/support/topic/ajax-doesnt-work-under-php8/#post-16451942) * As I see from the log file the issue is caused by the qtranslate plugin. * Please tell me – do you know if qtranslate plugin settings provide some option to exclude some URLs from its language redirections? * Regards * Thread Starter [Oleg Komarovskyi](https://wordpress.org/support/users/komarovski/) * (@komarovski) * [3 years, 4 months ago](https://wordpress.org/support/topic/ajax-doesnt-work-under-php8/#post-16464004) * 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.
