问题出现在插件'woocommerce xml feeds'中的wordpress管理控制台中。有按钮添加类别的参数。点击它时，此按钮不执行任何操作。
我试图联系插件的作者，他只告诉我检查调试控制台，但没有什么。他还告诉我，这个按钮的功能取决于jQuery。
这是按钮元素：
<span class="btn btn-danger btn-sm add-param" data-par="80">Přidat parametr</span>
上下文的整个PHP文件：

我真的试图谷歌它我发现类似的问题，一些简单的建议，切换到默认主题或将define('CONCATENATE_SCRIPTS', false);放到wp-config.php。没有运气这些。
