If a permanent link to non-default, like /% postname% / or other custom structures, user name if the number (001,999,1234 etc.) can not link to the profile.

Nobody found this problem? This seems to be a bug.

[@andrejcarter Participant 13 years, 1 month ago]

I don’t understand the question.

I’m sorry my English is a translation, perhaps picture can express more clearly.

Is the problem that you cannot get a users profile to show if the username is a number?

[@weiching-lin Participant 13 years, 1 month ago]

Correct, if the permalink is the default (http://domain.com/?p=123) do not have this problem.

[@andrejcarter Participant 13 years, 1 month ago]

I’ll see if I have the same problem on my test installation.

[@andrejcarter Participant 13 years, 1 month ago]

It won’t let me create a user without a letter in the username.
