Question

This has to do with media uploading in WordPress.

Every time WP creates a folder for new uploads (it organizes uploads by year and month: yyyy/mm), it creates it with the “apache:apache’ user and group, with full access to all (777 or drwxrwxrwx).

However, after that, WP cannot create a folder within that folder (e.g.: mkdir 2011 succeeds, but mkdir 2011/01 fails). Also, uploads cannot be moved into these newly created folders even though the permissions are 777 (rwxrwxrwx).

Once a month, I have to chown the newly created folders to be the same as user:group as the rest of the files. Once I do that, uploading works fine (which doesn’t make sense to me The really frustrating part is that this problem doesn’t exist in other WP installs on other domains on the same server.

* I wasn’t sure if this should be here or on serverfault.

Edit: The containing directory /.../httpdocs/blog/wp-content/uploads has the correct ownership

drwxrwxrwx 5 myuser psaserv 4096 Jun  3 18:38 uploads

This is a Plesk/CentOS environment hosted by Media Temple (dv).

I’ve written the following test script to simulate the problem

<pre><?php 

$d = "d" . mt_rand(100, 500);

var_dump(
    get_current_user(),
    $d,
    mkdir($d),
    chmod($d, 0777),
    mkdir("$d/$d"),
    chmod("$d/$d", 0777),
    fileowner($d),
    getmyuid()
);

The script always creates the first directory mkdir($d) successfully. On domain A, where the WP problem is, it cannot create the nested directory mkdir("$d/$d"). However, on domain B, both directories are successfully created.

I am running each script at /var/www/vhosts/domainA/httpdocs/tmp/t.php and /var/www/vhosts/domainB/httpdocs/tmp/t.php respectively I checked the permissions on tmp, httpdocs, and domain[AB] and they are the same for each path. The only thing that differs is the user.

Try going to your miscellaneous settings page (or media depending on your version) and make sure the upload directory is still wp-content/uploads.

If you need to. set the full url too.

Also, as a final solution, disable the option to organize them into folders so that way WordPress doesn’t even need to create folders.
