Fatal error: Call to undefined function wp_cache_get_last_changed()

  • I was trying to change the default video embed size settings in functions.php, and seem to have broken things somehow. When the provided code didn’t work, I deleted it and saved, but accidentally also deleted the line near the top about 

    require( ABSPATH . WPINC . '/option.php' );

    I reloaded my WordPress index page, saw an error and realized what happened, so I went to one of my other newly updated copies of WordPress and saved functions.php. I uploaded it to the site I was working on, but when I reloaded the WordPress index page I was still getting an error:
    Fatal error: Call to undefined function wp_cache_get_last_changed() in /home/flying/public_html/wp-includes/class-wp-term-query.php on line 668
    I tried googling that, but all the answers seemed to indicate that the user had installed a cache plug-in, but I don’t have any cache plug-ins on any of my sites.

    Any idea what went wrong, and how to fix it?

  • Core file wp-includes/functions.php could have been edited / deleted where this function has been defined.

    Depending upon your current WordPress version you might need to re-upload the correct functions.php core file and see if this resolves the current fatal error problem.
