警告：

AH01071: Got error 'PHP message: PHP Warning: strpos() expects parameter 1 to be string, array given in /var/www/vhosts/mysite.com/httpdocs/wp-includes/functions.php on line 4102\nPHP message: PHP Warning: strpos() expects parameter 1 to be string, array given in /var/www/vhosts/mysite.com/httpdocs/wp-includes/functions.php on line 4102\nPHP message: PHP Warning: strpos() expects parameter 1 to be string, array given in /var/www/vhosts/mysite.com/httpdocs/wp-includes/functions.php on line 4102\nPHP message: PHP Warning: strpos() expects parameter 1 to be string, array given in /var/www/vhosts/mysite.com/httpdocs/wp-includes/functions.php on line 4102\n', referer: mysite 

這裏是線4101 - 4103的functions.php的

function validate_file($file, $allowed_files = '') { 
    if (false !== strpos($file, '..')) 
     return 1;

這意味着你傳遞給strpos（$ file）的第一個參數不是一個字符串，而是一個數組。在調用strpos之前查看你實際擁有的價值之前，請先執行一行 var_dump($file)。

如果你有直接從文件格式的$ files數組，$ file ['tmp']是否可以。但最簡單的方法是var_dump。
