在模組管理最下面出現以下錯誤訊息，是否跟安裝模組有關係呢？
Warning [PHP]: is_dir(): Stat failed for /var/www/html/modules/netpbm (errno=13 - Permission denied) in file modules/system/admin/modulesadmin/modulesadmin.php line 101

那是 netpbm 模組的問題。

老師您好！再請問我在安裝 tadnew 及 tad_cbox 模組時，都會出現下列錯誤訊息，且告訴我Module File for Not Found！但是安裝其化模組（如piCal）時又是正常的，請問這有可能是什麼地方出問題呢？謝謝！
