Ok no answer but i solved my problem.
Some variables of "CB 1.2 - French - UTF-8 Language plugin" aren't exacts in cbteamplugins_language.php.
Exemple:
In cbteamplugins_language.php
'Created On : %s'
In cb.profilebook.php
'Created On: %s'
Only 1 space between "On" and ":" ...
I have "plug_cbprofilebook_1_2_RC2" version. I will correct "CB 1.2 - French - UTF-8 Language plugin" and add 1.2.1 variables.
