     Type:  defect (bug)        |     Status:  new
 Priority:  normal              |  Milestone:  Awaiting Review
Component:  WordPress.org Site  |    Version:  6.7.2
 Severity:  normal              |   Keywords:
  Focuses:  multisite           |
--------------------------------+-----------------------------
 A fatal error occurs when navigating to any site URL that contains '/wp-
 content/files/' on subdirectory multisites. Example: sitedomain.com/wp-
 content/files/

 The error is:
 PHP Fatal error:  Uncaught Error: Undefined constant "BLOGUPLOADDIR" in
 /www/site/public/wp-includes/ms-files.php:26

 This error does not occur when navigating to '/wp-content/files/' on
 subdomain multisites.

 This was tested on a new/fresh subdirectory multisite install, with the
 latest version of WordPress using a default theme, and the error still
 occurred.

 Steps to reproduce the problem:
 - On a multisite that uses subdirectories, go to '/wp-content/files/' and
 it should result in a critical error
 - Example: sitedomain.com/wp-content/files/
