我有一个用Wordpress Ninja Forms插件创建的表单。表格不会提交 - 它“坚持”处理..并且不会继续。 我已禁用其他插件，并尝试了不同的主题来查找错误。它仍然会发生。
这是Chrome控制台中出现的内容：
JQMIGRATE：已安装Migrate，版本1.4.1 /wp-admin/admin-ajax.php无法加载资源：服务器已响应 状态为404（未找到）前端.js：2错误：未找到 front-end.js：2 Object front-end.js：2 Parse Error front-end.js：2 注意：尝试重置grecaptcha时出错。 front-end.js：1未捕获 TypeError：无法读取未定义的属性“fields” at n.submitErrors（front-end.js：1） at _（backbone.min.js：1） 在m（backbone.min.js：1） at f（backbone.min.js：1） at u.Channel.u.trigger（backbone.min.js：1） at Object.error（front-end.js：2） 在我（jquery.js：2） at Object.fireWith [as rejectWith]（jquery.js：2） 在y（jquery.js：4） 在XMLHttpRequest.c（jquery.js：4） Link to Site
