上傳圖片的錯誤問題

在"我的帳號"/編輯/上傳圖片 測試看是否能正常運作,結果出現

* warning: copy(): SAFE MODE Restriction in effect. The script whose uid is 10382 is not allowed to access /var/www/vhosts/poper.com.tw/httpdocs/files/pictures owned by uid 48 in /var/www/vhosts/poper.com.tw/httpdocs/includes/file.inc on line 374.
* warning: copy(files/pictures/picture-1.jpg): failed to open stream: Success in /var/www/vhosts/poper.com.tw/httpdocs/includes/file.inc on line 374.
* 選擇的檔案 /var/www/vhosts/poper.com.tw/httpdocs/files/tmp/tmp_PCIqF0 無法被複製。
* 上傳圖片失敗；目錄 pictures 不存在。

但是在主機/files/pictures和/images 確實有存在,這樣是哪裡設定出錯呢?
