ERROR 404 in Category.

[andrenl]

Hi, when I try to brose, in frontend, in some category I get a 404 error from the server.
I realized that this error occurs when the alias category is only a number (ex. 2011), is there any way to fix this, or should I always edit the alias to something not numeric?

Thank you.
