Hi again,
I've solved my problem and it was related with .htaccess! I don't know why but I tried evertying to regenerate it except one thing.. I've grabbed another .htaccess from a developer instance that I have and replaced with the one that was causing problem, then I generated via friendly url and boom its working..
Would be intereseting to know what's causing this issue since many people in the forum are having this problem.
GL all.
