Can not edit item

I've created a profile for ICHILLIN' www.listal.com/ichillin%27, a k-pop group, but every time I try to edit it goes to the adress www.listal.com/ichillin/ and "Page not found
We could not find the page you were looking for" message appears.
I've tryed to edit using the www.listal.com/ichillin%27/edit and all goes well until I click the "save changes", whitch goes to the same www.listal.com/ichillin/ and "Page not found
We could not find the page you were looking for".
What can be done? Should I create a new profile just without the " ' " at the end??

I can't edit Lisa 'Left Eye' Lopes but every time I try to edit and press save change it goes to the address www.listal.com/lisa-/ can you fix it?
