一、ecshop标题中去powered by ecshop

\includes\lib_main.php:

$page_title = $GLOBALS['_CFG']['shop_title'] . ‘ - ‘ . ‘Powered by ECShop’;

修改为
$page_title = $GLOBALS['_CFG']['shop_title'] ;

二、删除底部版权：（删除不当底部版权会跑）

第一步：打开js/common.js,在txt里点看右下角，直到显示的是Ln244.然后从这里开始删掉到336行那里。删除后保存，
现在打开themes/default/library/ 这里default为你当前的主题，找到page_footer.lbi，里面内容全部删掉，添加上你想添加的代码。支持html代码的。完毕。
另外： 如果你只想简单的改下就弄第一步就行，然后去\languages\zh_cn 找common.php找到ecshop.com改成你网址，E CSho p对应改成你的网站名称就行，最后去themes\default\images里把logo1.gif改成你想要的图片，也就是左下角的那张.
*********************************************************************
2.7版本加入了JS控制，如果删除底部版权，则powered by ecshop会到处乱跑

用文本编辑器打开js目录里的common.js,V2.7.3的在261行-353行的代码保存退出,
其他版本的请自行搜索onload = function() 即可定位到

onload = function()

      link_arr[rmd_e].innerHTML = String.fromCharCode(

    }
  }
  catch(ex)
  {
  }
}

然后找到page_footer.lbi，把 后面的全部删掉，OK，整个世界清净了。。
这是随机在底部产生的!! 直接把这个函数去掉,底部的Powered by ECShop 就没了!!
