看了： project_tree_view插件修改，增加新增加子项目功能
redmine 1.1.3安装project_tree_view的bug修复403 You are not authorized to access this
也遇到类似错误，在浏览端显示错误信息： 403 You are not authorized to access this page
查看redmine 运行日志： $ tail -f apps/redmine/htdocs/log/production.log

reference ---> 参考上面的解决方法，无果！！！ 看来什么都是万能的。一切皆可能！！！
只有靠自己，依据之前解决的redmine问题经验，project_tree_view 对应的 vendor/plugins/projects_tree_view/app/views/projects/show.rhtml 文件，
与redmine默认的显示页面文件：vim apps/redmine/htdocs/app/views/projects/show.html.erb
有类似的功能或效果。
问题解决方法： 将错误的信息提示行的程序块，使用redmine默认显示页面文件代码替代，替代完就可以。
之前提示几次不同错误信息，一样的方法解决。
