去除方法有二：
方法一，增加新變量：
在后臺“系統/系統基本參數/增加新變量”，用新變量來代替默認的cfg_powerby標簽。
方法二，修改源碼:
通過比較6月7號的安全補丁，發現更新文件include/dedesql.class.php中下面的這段代碼明顯不正常，對比之前版本的include/dedesql.class.php文件，會發現最新的include/dedesql.class.php文件會多出第588到第592行的那幾段代碼，
$arrs1 = array(0×63,0×66,0×67,0x5f,0×70,0x6f,0×77,0×65,0×72,0×62,0×79);
$arrs2 = array(0×20,0x3c,0×61,0×20,0×68,0×72,0×65,0×66,0x3d,0×68,0×74,0×74,0×70,0x3a,0x2f,0x2f, 0×77,0×77,0×77,0x2e,0×64,0×65,0×64,0×65,0×63,0x6d,0×73,0x2e,0×63,0x6f,0x6d,0×20,0×74,0×61,0×72, 0×67,0×65,0×74,0x3d,0×27,0x5f,0×62,0x6c,0×61,0x6e,0x6b,0×27,0x3e,0×50,0x6f,0×77,0×65,0×72,0×20, 0×62,0×79,0×20,0×44,0×65,0×64,0×65,0×43,0x6d,0×73,0x3c,0x2f,0×61,0x3e);
把這段代碼刪除掉或者注釋掉，這個問題就得以解決了。
