WordPress Speed Up Service | WordPress Website Maintenance Packages Where must I put replaced functions?, by sherlock16 I created a child theme for Twenty Sixteen containing functions.php and styles.php. I believed that to replace a function I had to create a file named as the parent file and to put the redefined function there, but it is not working. I’m trying to redefine the twentysixteen_entry_date() function: if I put it into functions.php of the child theme it works, if I put it into the inc/template-tags.php file like the parent theme does, the redefinied functions is ignored. So, I guess the correct way is to put redefined functions into functions.php? Where must I put replaced functions?
