I am using twenty twelve theme. I want to relocate author and date to the space below the title of each post.
So in content.php, I pasted the entire code from footer to header.
So obviously the tags will show up over there too, but I only want the author name and date.
I also could not find any documentation for twentytwelve_entry_meta() to figure out how to somehow parse these information if it is related to this function.
You must use a Child Theme for these kinds of modifications to the default theme. Otherwise all your changes will be overwritten when WP is updated. Further, it’s crucial to have a clean copy of the default theme for troubleshooting. So back-up and make a child theme before you do this.
