Support » Fixing WordPress » 3.8 won't install

  • latest upgrade shows up in my wp blog. when i try to upgrade, i get this error message:

    Downloading update from…

    Unpacking the update…

    Verifying the unpacked files…

    Preparing to install the latest version…

    The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/js/revisions.min.js, wp-admin/js/revisions.js, wp-admin/includes/class-wp-upgrader-skins.php, wp-includes/js/heartbeat.min.js, wp-includes/js/wp-auth-check.min.js, wp-includes/js/zxcvbn.min.js, wp-includes/js/wp-auth-check.js, wp-includes/js/mediaelement/wp-mediaelement.js, wp-includes/js/heartbeat.js, wp-includes/js/zxcvbn-async.js, wp-includes/js/wp-util.js, wp-includes/css/wp-auth-check.min.css, wp-includes/css/wp-auth-check.css, wp-includes/date.php, wp-includes/post-formats.php

    Installation Failed


    now, i checked the permissions and all seem correct. folders 755 php files 644

    thoughts anybody?

    i should have also said that i tried to ftp the new 3.8, what happened was certain files in folders (e.g. wp_admin and wp-includes/images) would fail to load. so what i did was to go back to 3.7.1 and the near-same folders/files failed to load as well.

    now what should i do? my blog still works, i can still log into my admin, view my blog. i haven’t found anything yet to visually ‘fail’ or not work.
    it’s just that i can’t upgrade or get a ‘full’ ftp upload.

    I can’t get the latest version to download. I extracted all the files but I don’t see there it says to download. What am I doing wrong?

    you need an ftp program like cuteftp. it is easier to just go log into your wp admin, go to “Dashboard” and click on “Updates”

    There isn’t anything on my dashboard that says Updates. It actually says WordPress 3.7.1 is available! Please notify the site administrator. But I am the site administrator

    I’m a reasonable intelligent person but these directions are foreign to me.

    IS there anyone I can actually speak with who can walk to through this?

    What this means is that some of your files have incorrect file permissions or file ownership. You listed the set of files with the problem in the first post.

    You can see the file owner of those files via your FTP program, most likely. They will probably be different than the owner of the other files.

    If you have the ability to do so, you can try changing the owner of those files to be correct. But, you may have to contact your host and have them ensure that the ownership of all files in your account are set correctly, since you may not have access to change ownership yourself.

    Regardless, the updater failing here is a good thing. It’s protecting your site from being broken by an incomplete upgrade.

    WordPress is free software and this free, volunteer-staffed forum is the only support resource available via

    Which part are you having a problem with?

    It actually says WordPress 3.7.1 is available! Please notify the site administrator. But I am the site administrator

    Who runs your site? Who set it up for you? That’s who you need to talk to. Because either you’re not an “Administrator” on the site, or it’s a multisite and you’re not a “Super-Administrator” on the site.

    How do I deactivate plugins and then delete the old wp-includes and wp-admin directories on your web host (through your FTP or shell access).

    Do you know how to use FTP? Or whatever file management application your host provides?

    jbrunson: Please, if you’re having problems, start your own topic instead of piggybacking on the thread started by thealexangroup. It’s hard enough solving one problem, trying to solve two different people’s problems in the same thread is confusing.

    at ftp, does it go by any other name than ‘file owner’ or similar? i don’t have anything near that wording. ftp shows ‘address’,’remote’,’item name’, etc.

    here’s the thing. my other wp blogs are near-similar in content/set up. they updated with no problem. (updated from wp blog admin)

    most likely will have to let host support take a look.

    thanx for your assistance regardless.

    All FTP programs can show owner in some manner, but how to see it depends on the program. You mentioned CuteFTP above. I know it displays a file list in columns. Try clicking on those columns and seeing if there is an “owner” column that isn’t displayed by default.
