Can't use .htaccess

[yojoe]

1. The website address is http://www.buppodojo.it/
2. The webmaster wants me to help him convert the site to Get-Simple. 3. I don't know who the hosting company is.
4. There is no "users" folder in the data folder. Should I create one?
--Thanks.

Looks like the website is being hosted by tiscali.it (http://business.tiscali.it/hosting_domini/)
I suggest you to look for a real webhosting company, who focus only on hosting services, not on everything possible.
I'm also unable to find out if apache is the webserver.

ad4. it's impossible that there's no /data/users directory, which doesn't contain a file with your user profile.
Otherwise you wouldn't be able to login to admin panel.
Check once again to be sure that you have uploaded all files.
It's a common problem with uploading CMS files through FTP applications, where some of the files at the end are missing.
