Something I noticed a moment ago (and please correct me if this doesn’t happen for everyone):
Trying to go to ketogenicforums.com:
ketogenicforums.com’s server DNS address could not be found.
Trying to go to www.ketogenicforums.com:
Site loads as expected.
I wanted to point this out as most sites will automatically forward root URLs to the /www/ folder for the convenience of visitors. Not sure if you’re using nginx or apache as a web server, but your hosting company should be able to help you out with this.
