EDIT: Problems has solved from Datahell suggestions

The following applies only to Elxis 2008.1

Elxis 2008.1's htaccess is diferrent than the 2008.0's.

Sites on www root folder
Just rename it to .htaccess and you are ready.

Nice site!
Make cache/ folder writable! Don't display administration login page link in public. Don't display user only links in public (i.e. edit profile)!
