Articles links on my WordPress website don't work
The Homepage https://braperucci.com works fine but article links, categories etc don't work.
I get a 404 Not Found Error
It does look like you've managed to resolve this. For any others who may be facing a similar issue the most common reason for this problem is if rewrites are not enabled in Apache (LAMP) or you have not made additional configuration changes required to run WordPress on Nginx (LEMP).
If you are using Apache you will want to run the following commands:
sudo a2enmod rewrite sudo service apache2 restart
