I find a solution to my problem.
I put id_parent value of home identifier (2 in my case) to all my categories. Now I can see the categories tree in products also into edit categories menu on mi back office.
Prestashop version 1.6.08
I have the same problem. In the backoffice when edit a category or a product, the categories tree does not charge. Is nothing rendered.
I don't know the solution
Mismo problema en el configurador del tema para la version de prestashop 1.6.0.9 y los logos, el favicon. Al añadir los nuevos desaparecen los de por defecto y no cargan ninguno.
