if a user have username only by numbers, just like "560560" i cannot see users cb profile when i clicked on profile link of that user.
the link is:


[code:1]www.xxmydomain.com/component/comprofiler/userprofile/560560.html[/code:1]


if I change the user name to "560560a" i can see the profile and the link of profile
changed to:


[code:1]www.xxmydomain.com/component/comprofiler/userprofile/560560a.html
[/code:1]

how should I fix this, is this a core sef problem or cb problem?
