GCal identification problem ?

Hi there,

I let you access to my website in order you to check the following problem.
After an update I had the message : "Appointments +: Google Calendar Settings have changed on version 1.7. If you have been using Google Calendar prior to 1.7 please review your settings. "

So I went check out and re-entered my GCal id. But when I finish the last step "1 Generate your access code," then "2 Fill the form below", the form stay blank after udpating.

Is that a normal behavior ?

Thanks a lot!
