[PS - 1.7.6.4] - Disconnection when the customer enters his address

[droucache]

Hello,

I find myself facing a rather annoying concern. Indeed when a customer places an order on my site, at the time of identification, he enters his name, first name, email and if he wishes (to register) his password.

He validates and finds himself entering his address ... except that at that time, if he clicks on the page or in the fields to be completed, it returns a logout (emptying of the basket and disconnection).

It does not happen if he does not go through the mdp and only registers as a guest.

thank you in advance for your help

By looking a little (a lot), I have a track.

Indeed, I integrated the English language into the site and by choosing English, it works.

Any idea what would block on the French language?

Thank you
