Ecshop是著名的B2C商城开源程序，很多朋友采用Ecshop进行二次开发，但是Ecshop对于未商业授权版本进行了版权限制，主要表现在以下两个地方：
1。标题后面显示：powered by ecshop v2.7.2
2。底部显示:powered by ecshop v2.7.2
按照国际开源协议，未商业授权的开源软件不能应用于商业活动，但是目前国内很多小企业为了降低成本同时兼顾网站美观效果，希望去掉这些开源软件的版 权，大秦数据工程师为大家提供一种方式可以去掉Ecshop V2.7.2的版权，不过我们希望有实力的公司还是购买Ecshop的商业授权。
如何去掉Ecshop V2.7.2头部版权信息：powered by Ecshop V2.72
方法：
打开 ecshop根目录/includes/lib_main.php, 找到如下代码:
/* 初始化“页面标题”和“当前位置” */
$page_title = $GLOBALS['_CFG']['shop_title'] . ' - ' . 'Powered by ECShop';
$ur_here = '<a href="." mce_href=".">' . $GLOBALS['_LANG']['home'] . '</a>';
将蓝色部分删除或修改为自己的网站信息.
如何去掉Ecshop V2.7.2底部版权信息：powered by Ecshop V2.7.2
方法：打开ecshop2.7.2的themes/default/library/page_footer.lbi文件， 将以下代码删除
{foreach from=$lang.p_y item=pv}{$pv}{/foreach}{$licensed}
打开js/common.js， 该文件第261行到第353行代码删除。就是以下代码
onload = function() { var link_arr =
document.getElementsByTagName(String.fromCharCode(65)); var link_str;
