The problem happened due to a corrupted .htaccess,
After all the stages above, I removed Wordfence with wp plugin uninstall and then, after that, I recreated the .htaccess based on the formal example here:
https://codex.wordpress.org/htaccess
I saved and relaunched the site and now it’s working.
When the site is up reactivate all plugins and bring back Wordfence.
