Prestashop on Altervista

Hi all,
I am trying to install Prestashop for Altervista.

I have a problem during the store installation (it looks during the installation of the database tables), as show in the following image:

Do you have any suggestion?
Thanks

Delete all the Prestashop tables from the database, unlock the server to server whitelist from the AlterVista control panel (look at the PHP settings), then in the file of Prestashop classes/Tools.php find

if (in_array(ini_get('allow_url_fopen'), array('On', 'on', '1')) || !preg_match('/^https?:\/\//', $url)) 

and replace it with

/*if (in_array(ini_get('allow_url_fopen'), array('On', 'on', '1')) || !preg_match('/^https?:\/\//', $url)) 

below that, find

elseif (function_exists('curl_init')) 

and replace it with

else*/if (function_exists('curl_init')) 

And finally try again the installation procedure.
Let me know if you have any other issue.
