Unable to activate HTTPS

Hi,
I've been trying to activate HTTPS and update my phone number on my profile so I can receive an SMS for identification but I've just been unable to do either for some reason. Every time I try to save the changes made on my profile I get the message "invalid zip".
Thanks in advance,
Eiga9

Could you please provide your telephone number in private message?

Thanks
Bye!

Hello,

Could you please try now?

Thanks.

Bye!

Hello,

I have the same problem: I've been trying to activate th HTTPS service but I don't get the SMS on my phone (a French cellphone). Would it be possible to sort this out?

Thanks in advance!
