Member URL Structure
I am seeing an issue which also exists here on this forum. The users profile is being displayed if you enter a userid or the users nicename.
The problem is if users have usernames which are just numbers, then the profile is shown for the matching userid and not matching nicename. This is the case with the setting set to use /NICENAME/
Shouldn't the setting force the use of nicename and therefore the /1 should return an error as no user with a nicename matches?
