Error: Couldn't open config file "awstats.rovito.conf" nor "awstats.conf". Please read the documentation for directories where the configuration file should be located.

- Did you use the correct URL ?
Example: http://localhost/awstats/awstats.pl?config=mysite
Example: http://127.0.0.1/cgi-bin/awstats.pl?config=mysite
- Did you create your config file 'awstats.rovito.conf' ?
If not, you can run "awstats_configure.pl" from command line, or create it manually.

Check config file, permissions and AWStats documentation (in 'docs' directory).
