什麼是導致此權限的錯誤，我該如何解決它？

警告：move_uploaded_file（/home/site/public_html/wp-content/themes/mytheme/upgrader.zip）[function.move-uploaded-file]：無法打開流：權限在/ home/site/public_html/wp-content/themes/mytheme/uploader.php on line 79什麼是導致此權限的錯誤，我該如何解決它？

Warning：move_uploaded_file（）[function.move-uploaded-file]：無法將'/ tmp/phptempfile'移動到'/ home/site/public_html /wp-content/themes/mytheme/upgrader.zip'在線79 /home/site/public_html/wp-content/themes/mytheme/uploader.php有問題。抱歉!

代碼低於該行...

只是觀察：您檢查上傳文件的MIME類型，然後用$'$ = = strtolower（$ name [1]）=='zip'這行來丟棄檢查結果？ true：false;' – Dancrumb 2010-03-19 14:52:15
