1、一般情况下呢，在模板的foot.htm是可以找到power by dedecms的，直接删除就可以了；但有的模板可不是这个样子，下边主要针对这样的情况介绍一种去除方法：
（1）打开文件：网站根目录/include/dedesql.class.php
（2）打开dedesql.class.php后，通常在588-592行有下面代码：
$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79);
$arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f,
0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72,
0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20,
0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e);
将这段代码更改成下面代码，就可以了：
$arrs1 = array();
$arrs2 = array();
之后生成网站，查看一下底部版权中的Power by DedeCms就去除了
