Unable to add header for the website in header.tpl using OpenCart

Question

我尝试在header.tpl中添加标头，但它并没有反映在前端，我为测试网站做了同样的操作，一切都很好，请您提出一种编辑方法，告诉我是否需要更改某些内容任何其他header.php文件

Answer 1

In your admin panel, go to Extensions > Modifications and hit "Refresh" (the blue icon in the top right corner of your page).

This process must be done every time you change something in a core file.

Changing OpenCart's core files is not a great idea, though. I highly recommend using OCMOD to write your modifications.
