您好，请问是什么版本的？

斑竹，是jeecms-2.4.2-final？
希望你能帮忙下，看看怎么解决？

并且：当前位置： 下载系统 - 软件类型 - 添加
无法写入数据！程序也不报错。。

您好，您是不是改动源代码了，我这里是可以正常添加的，您这里显示的错误是contentCtgList[0]这个没定义

没有斑竹，源码从来都没动过！是从你们那里下载的。。。
var attrMap = {};
<#list contentCtgList as attr>
attrMap['${attr.id}'] = [${attr.imgWidth},${attr.imgHeight}];
</#list>
我查找提示的错误：\jeecms\WEB-INF\download_sys\download 里面的：add.html
程序在这里没有输出数据；
奇怪的是，在你们的jeecms演示网站里面正常，出现错误是在我添加的新站点里面；

您好，您新站点跟我们的站点对照一下，看看是不是哪里改了，这个功能是肯定有的，可能是您的新站点哪里出错了。

哦，斑竹的意思是程序没问题！
但是我是按照流程来添加站点的，其他栏目，功能好像正常！
是否有必要重新安装下程序？
如果是数据的问题，我们也不好查找原因！！

您好，您看看您新站点，后台文章内容里面的内容属性有没有添加
