I can't change my username.It says You can't changed username while you logged into live chess.I'm not in live chess.I close the page already.

Help me,please.

Are you sure that another device isn't connected to live chess?

yes

click" home" to reset things

Any phones or tablets you were using might need to be logged-off, rather than just close/switch off the device.

Thanks.I'll check if my ipad has to do with this.

Might it be a tab hidden..Task bar!

Could be, or a window open "underneath".

I fix it.Thanks for your help.

Can you tell us how you fixed it? 

No name change happened.

Members can change their username once via their 'edit profile' page.

My username used to be IamAlittlePrincess but boys were mean to me so I changed it. Kohai let me 

I know how I fixed it; and I will actually share the answer with folks instead of stringing them along:

Just close all open browser sessions; clear cache, history, etc.  Reload chess.com, sign in, and go to the page for making a name change.  You should have no problem doing it.

Its on this page

http://www.chess.com/home/edit_profile

It allows people to change their own username. The system will only allow one name change regardless of clear cache :)

Yes; but there is a separate error not related to the number of changes that prevents even the one change.  It is the error that was mentioned in the OP and for which the solution I posted should work well.

Oh,i think it is too late for me to post this.

I fix it through this method.Even you never enter live chess page and play,you are consider a live chess user since you logged in the first time to it.

So,you just enter the online chess page and logged it there,then you're registered as online chess user for now until you mkae your next log into live chess.

I wonder if staff of chess.com can solve this bug ?

I've tried all the suggestions (reloaded page, pressed "Home", deleted cache and history, restarted browser, restarted COMPUTER, logged in from different places on the site) and I'm still receiving that same annoying "live chess" message. Can someone on the staff help me change my username? please :)
