Hi sorry my poor english ,

When someone register for the first to my website , all field are writeable... but when they login (account are actif) and they go to their profil page and they try to edit information ... they only can change name email but others field they can't change they are like locked ?

a option that I forget ?

In your admin, go to CB Field Management.
Choose your field you created.
Scroll dow and make sure you havent set "read only" to yes.

it should be "no" if you want them to be able to edit it
