我网站标题中的错误消息 - 如何修复？ [关闭]

Question

I have an error message appearing in the header section of my site and don't know what's the reason for that. It seems like a bug but I don't know the reason and how to fix that!

Answer 1

It appears that your site is trying to set something on the header (perhaps a cookie) after the response was sent. We need to see the code responsible. Most likely you need to move some of your code around in your file (perhaps the thing on line 8 should be before the thing on line 1?)
