我面临dsIDXpress Pro搜索问题。

每次我试图更改搜索词时，网站都会出现403错误。http://lagunaagent.com/idx/city/laguna-niguel/

从错误中解脱出来。日志

    if (isset($seo_keywords) || isset($seo_description) || isset($seo_title)) {
        $dsidxpress_seo = new dsidxpress_seo($seo_title, $seo_description, $seo_keywords);
        add_action(\'wp_head\', array($dsidxpress_seo, \'dsidxpress_head_action\'));
        add_filter(\'wp_title\', array($dsidxpress_seo, \'dsidxpress_title_filter\'));
    }

我已经对更改主题（2111）和打开/关闭插件进行了一些故障排除，但没有结果。
