Thank you very much for your answer!
I was able to solve my problem! the website is working now and the redirection is also working!
What I was trying to do was redirecting my .com.br to wordpress.com and got stuck with the database name because I read on that first link that it was the way to achieve it.
The thing is actually ver simple and I found the solution here: https://tudosobrehospedagemdesites.com.br/redirecionar-dominio-pelo-registro-br/#comment-6745
For someone that got stuck with the same problem, I’ll explain the steps I took:
I bought the domain at registro.br and created a free account at wordpress…
In registro.br they have a basic interface where it’s very easy to set up the redirection, but if you want to set up an e-mail, you’ll need to migrate to the advanced interface.
Once you do that, the basic interface set ups will no longer work.
I asked for help to the registro.br customer service, but they didn’t help me at all… Later, I found out (wrongly) that my hosting provider was Cloudflare, so I created an account here.
I changed the DNS servers to the ones that Cloudflare pointed to me. It took 2 hours and at that point I became able to manage the DNS records at Cloudflare. I just copied what I did so far at registro.br and it worked fine. I could send and receive e-mails.
The next step was to set up the redirection in the advanced mode. That was the moment I used the tutorial on a specific comment in the link above.
Basically I did the following at “DNS” field:
Later, I went to the “page rules” field and did the following:
It’s working pretty well now!
I think you may be able to do that without leaving registro.br, but it’s probably easier that way.
Will work on the content of the website now! thank you all for the kind responses!
