DONE!
I am very happy to tell you all that finally 1.5.5a is on line!
For a small business like mine and considering I do no use any web agency neither programmer or graphic (I do all on my own, with the precious help of this forum) it is a real success.
I still have a problem though and it is related to ssl

I have set HTTP server as https and to false in both store and admin.
I did not like the fact that if I call http://www.acquat ua.it it does not go directly to https://www.acquat ua.it so I mde a mod to the htaccess like follows
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}/$1 [R=301,L]
This actually did the job and also non https request is redirected to https Yeah! but...
If I let the htacces as above, livelizza would not allow to login, if I disable the two lines livezilla will login perfectly.
Now for the questions:

As far as the big G and others are involved, is it important that http is redirected to https since the first page?
If what above is true, how can I make livezilla login even with http redirected to https?

Note that in the livezilla serve admin I have set the server to be https and the port 443.

It is not a mjor problem but I have started this migration with the ami to create the best possible setting and this is bothering me.

Thanks for help.
