Plugin doesn't have support for multi-language plugins

[JoaoFreitas2002]

I am using Polylang plugin and no matter the language, always return the same page.

I don't know how the other multi-language plugin work, but for polylang you can change the function to this:

public function custom_404_pro_redirect()
{
    global $wpdb;
    if (is_404()) {
        $sql                     = 'SELECT * FROM ' . $wpdb->prefix . $this->helpers->table_options;
        $sql_result              = $wpdb->get_results($sql);
        $row_mode                = $sql_result[0];
        $row_mode_page           = $sql_result[1];
        $row_mode_url            = $sql_result[2];
        $row_send_email          = $sql_result[3];
        $row_logging_enabled     = $sql_result[4];
        $row_redirect_error_code = $sql_result[5];
        if ($row_logging_enabled->value) {
            self::custom_404_pro_log($row_send_email->value);
        }
        if ($row_mode->value === "page") {
            $page = get_post($row_mode_page->value);

        //Polylang
        if (function_exists("pll_get_post")) {
            $translated_page_id = pll_get_post($row_mode_page->value, pll_current_language());
            $page = get_post($translated_page_id);
        }

            wp_redirect($page->guid, $row_redirect_error_code->value);
        } elseif ($row_mode->value === 'url') {
            wp_redirect($row_mode_url->value, $row_redirect_error_code->value);
        }
    }
}
