最近由于织梦DEDECMS程序6月份的漏洞，很多织梦网站都被黑了，所以大家都在抓紧时间更新系统补丁。
但是这次的DEDECMS V5.7版本更新后，在前台网页底部会出现织梦版权信息 “powered by dedecms”，很多人都不知道怎么去掉的（不建议你去掉，毕竟程序是人家开发的，你免费用了），因为这段代码并不存在于HTM模板中。
怎么去除织梦底部的 powered by dedecms版权信息：
在
include/dedesql.classs.php文件中找到第588行：
1
$arrs1 = array(0x63,0x66,0x67,0x5f,0x70,0x6f,0x77,0x65,0x72,0x62,0x79);
2
$arrs2 = array(0x20,0x3c,0x61,0x20,0x68,0x72,0x65,0x66,0x3d,0x68,0x74,0x74,0x70,0x3a,0x2f,0x2f,
3
0x77,0x77,0x77,0x2e,0x64,0x65,0x64,0x65,0x63,0x6d,0x73,0x2e,0x63,0x6f,0x6d,0x20,0x74,0x61,0x72,
4
0x67,0x65,0x74,0x3d,0x27,0x5f,0x62,0x6c,0x61,0x6e,0x6b,0x27,0x3e,0x50,0x6f,0x77,0x65,0x72,0x20,
5
0x62,0x79,0x20,0x44,0x65,0x64,0x65,0x43,0x6d,0x73,0x3c,0x2f,0x61,0x3e);
改成：
1
$arrs1 = array();
2
$arrs2 = array();
保存文件并上传即可。大家如果觉得实在影响美观或者怕导出权重，建议去掉后在网页首页友情留个官方链接或者底部信息留个powered by dedecms 不带链接即可，请大家尊重版权哈！
