如何在 wordpress post 中显示 "Published on"-date 而不是 "Last edited"-date

How to show "Published on"-date instead of "Last edited"-date in wordpress post's

我有一个博客的主题,我正在尝试修改它,所以每次我编辑它时它总是显示 "published date" 而不是 "Edited on"...

我已将它钉在文件中 -> functions.php 显示日期的地方... "Posted On Function"

部分

但每次我尝试修改 if/else 时,我都会在页面上收到错误 500 :-(

在此非常感谢您的帮助...

提前致谢!

-最好的问候

我怀疑的部分是原因:
