Upgrade to 4.2.3 fails!

Try MANUAL updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old copies of files & folder on your server before uploading the new ones. Read the Manual Update directions first.
– If you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong.

Ok, however, that sounds like a major pain. Is there a way just to fix the inconsistent file permissions?

What should the permissions be…this is a windows server?

Ok, I figured it out. I just had to give the Iusr account permissions.

I am having the same issue as “salescart” but I don;t understand what you;’re talking about with “lusr account permissions”. Can someone give me some more info on why i’m failing to update WP to version 4.2.3?

This is what i’m seeing:

“The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php”

On Windows, there is the IUSR account which represents the “web browser” essentially. In my case, this website is not yet visible to the public so the IUSR permissions did not exist. I’m not sure exactly what permissions you need to give the ISUR account since we gave it Change/modify permission and then removed it again afterwards. However, I’m guessing you need to give the IUSR account at least RX (Read Execute) permissions. That was the original purpose of my thread as I’m unsure of exactly “where” or “what” the “correct” NT file permissions are documented for Windows machines.
