how are you?
I have a wordpress multisite and my main page is http://www.chablau.com.br and a subsite ( http://chablau.com.br/blog ). if the subsite url is used with a 'www', it returns a 404 error.
If I change the subsite domain to www.chablau.com.br/blog, the url without the 'www' will send me to the main site homepage
eg.: `http://chablau.com.br/blog/` works fine
`http://www.chablau.com.br/blog returns` a 404 error
Someone has any clue about what is happenning ? bellow it, you can find what is in my .htaccess

the issue I think is your virtual host setup is using "domain chablau.com.br" however it should be "www.chablau.com.br" and then you add a rule in your htaccess that redirects non www to www will solve your issue
