Looks like you're having some DNS problems.
There's a handful of things that could be generating this problem.
- If you've just acquired the domain name, or server recently, there's a chance the domain hasn't fully propagate. It might take up to 24+ hours for a new domain to fully propagate.
- If you previously had a website installed on this host, deleted it, and now reinstalled a new software, there's a chance the account reset hasn't been done properly. Leaving some files behind such as .htaccess and such. Or the Hosting hasn't fully processed this change.
- Make sure your Q2A domain is pointed to foro.rme-systems.ml in Q2A Admin Settings, and not for the main directory rme-systems.ml .
But I believe it's the first option, so wait 24h, if your website still hasn't updated, get in touch with your hosting provider to help you fix this DNS connection problem.
