I tryed to fix it and failed, also asked somebody with more experience to do it and he also couldnt fix it. I have lost so much time thatis better to start again.
I am installing Bitnami.prestashop all again.
Which folders should I replace (without ¨breaking¨ the data base) in order to make my new Prestashop page as similar as posible to how it was before all this problem?
I still have acces to the Bitnami folder, with the child theme I was using, some configuration and pictures saved.
