I already did, Sofy. You have the pic of the phrases in my previous post. And, yes, I did clear the Phrase cache (and then all caches as well).

I've had this issue with "Nickname" and a few others like that, too, albeit I was able to change some of them using the addon User Custom Fields. Here, I'm stuck. 

This is a very small issue, I know. But I also know that many members won't be able to put up with it. This is France.  😎 

@alain,

Please see screenshots:

try to add a phrase  " I allow to create an account and send confirmation email . "   (with a full stop).

Still no luck... Maybe I should delete the "wrong phrase"? But how? Where is this stored? 

Hi @alain,
