Help: Undefined Function: 2.3 won’t run

  • I upgraded to 2.3 and I am getting this error:

    Fatal error: Call to undefined function: update_post_caches() in /home/content/n/a/m/nam6641/html/wordpress2/wp-includes/query.php on line 1312

    So I cannot access my blog at all. Any help with what this error means and how to correct? Thanks!!!!

  • That function is defined in wp-includes/post.php file – make sure you have it uploaded and unaltered.
    Eventually, try to upload a fresh copy of it.
