WordPress的 - 文件（/）是不是在允许的路径（S）

Question

我有一个移动的WordPress到我的服务器后，一些奇怪的东西中：

Wed Aug 27 18:10:43 2014] [warn] [client 77.21.106.179] mod_fcgid: stderr: PHP Warning: is_dir(): open_basedir restriction in effect. File(/) is not within the allowed path(s): (/var/www/vhosts/xyz/:/tmp/:/usr/share/pear/) in /var/www/vhosts/xyz/xyz/wp-includes/functions.php on line 1425 

为什么WordPress的尝试的访问/？有任何想法吗？

在呼吁的WordPress的1GB ERR-日志将产生^^

我做主持人大约100 WP情况下，都做的非常好，没有安装改掉以访问“/”。

这是函数至极失败：

function wp_mkdir_p($target) { 
    $wrapper = null; 

    // strip the protocol 
    if(wp_is_stream($target)) { 
     list($wrapper, $target) = explode('://', $target, 2); 
    } 

    // from php.net/mkdir user contributed notes 
    $target = str_replace('//', '/', $target); 

    // put the wrapper back on the target 
    if($wrapper !== null) { 
     $target = $wrapper . '://' . $target; 
    } 

    // safe mode fails with a trailing slash under certain PHP versions. 
    $target = rtrim($target, '/'); // Use rtrim() instead of untrailingslashit to avoid formatting.php dependency. 
    if (empty($target)) 
     $target = '/'; 

    if (file_exists($target)) 
     return @is_dir($target); 


    // We need to find the permissions of the parent folder that exists and inherit that. 
    $target_parent = dirname($target); 

    // MY MODIFICATION 
    if ($target_parent = '/') { 
     var_dump($target, $target_parent); 
     die(debug_print_backtrace()); 
    } 
    // MY MODIFICATION END 

    while ('.' != $target_parent && ! is_dir($target_parent)) { 
     $target_parent = dirname($target_parent); 
    } 

    // Get the permission bits. 
    $dir_perms = false; 
    if ($stat = @stat($target_parent)) { 
     $dir_perms = $stat['mode'] & 0007777; 
    } else { 
     $dir_perms = 0777; 
    } 

    if (@mkdir($target, $dir_perms, true)) { 

     // If a umask is set that modifies $dir_perms, we'll have to re-set the $dir_perms correctly with chmod() 
     if ($dir_perms != ($dir_perms & ~umask())) { 
      $folder_parts = explode('/', substr($target, strlen($target_parent) + 1)); 
      for ($i = 1; $i <= count($folder_parts); $i++) { 
       @chmod($target_parent . '/' . implode('/', array_slice($folder_parts, 0, $i)), $dir_perms); 
      } 
     } 

     return true; 
    } 

    return false; 
} 

我增加了一些修改，阅读评论找到它，我得到以下输出：

string(95) "/var/www/vhosts/xyz/xyz.kunden.xyz/wp-content/uploads/2014/09"

什么是不正确的，因为dirname（/var/www/vhosts/xyz/xyz.kunden.xyz/wp-content/uploads/2014/09）应该返回/var/www/vhosts/xyz/xyz.kunden.xyz/wp- content/uploads/2014，而不仅仅是/ ...

有什么想法吗？

仔细检查$target中的路径确实存在。在使用不同的内部文件夹设置将Wordpresses从一台服务器移动到另一台服务器之后，发生了此错误。

如果服务器上不存在$target中的路径，则需要在代码和数据库中更正每次出现的路径。

为了安全地更正数据库中的值，请使用像https://github.com/interconnectit/Search-Replace-DB这样的工具来处理数据库中类似字典的结构。
