discuz x2自發布以來很多網友希望能夠去掉discuz版權,其實做二次開發代碼也要考慮discuz既然開放給大家使用了,大家也厚道一點,起碼保留一下版權,這是尊重知識產權的基本原則吧,站在網友的立場上本人放出詳細去discuz版權的教程,也可以說是完美去版權了,最后提醒大家“慎用！”如有網友侵權引起糾紛,與本人無關,我只是站在技術角度去二次開發,謝謝配合！
一、去除頭部版權
在原來的discuz X2版本中，標題中去掉“Powered by Discuz!”版權標識很容易，只需要修改模板文件的頭部公用文件，將“Powered by Discuz!”這一行字去掉即可。
但是discuz X2 似乎對這點有所防備，把-Powered by Discuz!中的-放在了變量里，所以刪除后，標題一句話結束后會有一個小-尾巴，對搜索引擎很不友好，所以也有一個好的辦法完美解決，即：
打開/template/default/common/header_common.htm文件，找到<title><!–{if !empty($navtitle)}–>$navtitle – <!–{/if}–><!–{if empty($nobbname)}–> $_G['setting']['bbname']-<!–{/if}–>Powered by Discuz!</title>
將其中的“Powered By Discuz!”字串改為“{lang secondtitle}”。
再打開source/language/lang_template.php?！≡谧兞康淖詈螅簿褪钦麄€數組的目錄后按以前的格式，加上“‘secondtitle’ => ‘你的論壇名稱!”,” 。
更新緩存即可。
二、去除底部的版本
打開template/default/common，找到footer.htm文件，用deamweaver打開，點擊編輯，再點擊查找和替換powerd by，知道相應的位置把底部版權的相應內容改了就ok了，注意修改下面紅色標記部分
</div>
