HELP Webalizer reporting: No Apache logs ....

I go on virtualmin system and setting validate virtual server validated now and tells me:
Beginning validation of selected virtual servers. Any problems found will be shown in red …
Webalizer reporting: No Apache logs found for virtual host
Log files rotation: No Apache logs found for virtual host

What should set to resolve these two errors

Maybe website logging ? Just a guess there.

Excuse but I do not understand, do not speak English and use google translate to translate, if you can be a bit more specific thank you

if i go to I get to see this
