@text_cut s=tag_bean.desc
提示你这个标签有错，你怎么写的

这样 <p class="iproname1">[@cms_content id ='597']
                            [@text_cut s=tag_bean.desc len=500 /]
                            [/@cms_content]</p>

你这条内容是不是没摘要

我运行服务器，就出错了，摘要有呢

[@cms_content id='']
${tag_bean.description!}
[/@cms_content]

这样写也会报同样的错误
