Ok, so just based on what you are saying, I’d guess there is something misconfigured with the actual localhost. If you create a folder, and create a simple index.php file, when you view that index page in a browser you should definitely see the contents. If this isn’t the case, then WordPress will certainly not work.

Curious, how do you have this localhost setup?
Can you confirm everything is setup correctly?

Thanks for answering to my issue.

I was writing a response to your answer, and start to test again, and it happens to be the cache of the browser, and it is working now.

I’m sorry for what a newbie error.

Regards,
Javier
