我有一个kohana框架的表单构建，应该发送一封电子邮件。
当我按下“发送”按钮时，一切似乎都工作正常......没有错误消息......但没有电子邮件出现！
如果我无法在萤火虫中看到任何东西......我在哪里可以看到？
应用程序记录状态
“错误：缺少i18n条目contact.captcha.valid for language en_US”
但我不知道如何找到问题的根源......欢迎任何帮助.. 你的，
罗布
我试着找出使用哪个版本.....应用程序是Ushahidi的最新版本（2.2.1）www.ushahidi.com

从提供的小细节来看，我认为您的网站使用Kohana的I18n库来实现网站的国际化。另一个选择是您的网站使用Kohana消息来显示表单错误。
验证类在生成验证错误时在内部使用__（）函数。我认为您没有valid中指定的密钥APPPATH/messages/contact/captcha.php的消息。
您应该尝试更多地了解表单的处理方式以及是否生成某些验证错误。验证码验证中可能存在错误，尽管看起来没有错误，但可能存在错误消息，但无法显示错误消息。

我的问题已经解决了！
我的电子邮件服务器设置不正确。我解决了后缀问题，现在评论表格正常工作，
感谢所有回答的人，罗布
