自定义订阅表单会产生可怕的错误。
警告：无法修改标题信息 - 已经发送的标题（/customers/3/3/a/website.nl/httpd.www/aanmelden/contactengine.php:87中的输出）/ customers / 3/3第89行/a/website.nl/httpd.www/aanmelden/contactengine.php
联系引擎不会发送表单，它显示此错误。 并弹出不会发送消息的JavaScript错误。
有人有什么建议吗？

答案 0 :(得分：0)
我不知道为什么会出现标头问题的确切原因，但是您可以通过使用JavaScript的window.location代替PHP的标头重定向来解决此问题。
替换
header('Location: index.php');
用
echo("<script>window.location='index.php';</script>");
并替换
header('Location: http://www.website.com/aanmelden/index.php');
使用
echo("<script>window.location='http://www.website.com/aanmelden/index.php';</script>");
希望它有所帮助！
