I am working on an old WordPress site. Although the site is updated to the latest version of WordPress (5.9.1) it was apparently built on the twentyfouteeen theme.
Just lately, I am getting a fatal error on the Posts Page:
Fatal error: Uncaught Error: Call to undefined function twentyfourteen_categorized_blog()
The function is located in the template-tags.php file and it exists so the theme should be able to access it. In fact, I’m getting the fatal error on any page that calls a twentyfourteen function.
I copied the functions from template-tags.php to content.php which did in fact load posts but then gave me a different error Cannot redeclare twentyfourteen_categorized_blog()
I’ve never had to troubleshoot this kind of error and since the theme is old, I’m not sure how to go about it.

I was able to resolve this by including template_tags.php in functions.php
"Cannot redeclare twentyfourteen_categorized_blog()" means that your file is trying to declare the same function multiple times. Either the function is defined in two separate files or in two places in the same file.
