我要建一个食谱网站，正好drupal有第三方模块叫做recipe
在新建之后一切正常，注册用户可以发表文章（我并未赋予权限）
在我赋予了权限之后，反而他们不能发表文章了，（在创建文章内容的时候没有那个recipe的选项了），再反复赋予与取消之后，均不行。
经过测试，并未与其他模块或者翻译相冲突，请问这是为什么啊。。。。。。

Because I come from mainland of China ,so I don't know if you can understand my simplechinese,so I translate it into English

I want to build a recipe site,and there is a module called "recipe" ,so I use it ,and when I start the site,it's just OK,the Registered Users can publish their content (I even didn't give them the permission.)
When I give them the perission,or even I just visit the "permission page" ,they can not publish their recipe content .
I tried several times ,it still can not work.
after the test ,I think it will not be conflict with other modules,please help me ,thanks very much!!!!
