Child theme dont override parent

[María_Amieva]

Hi.

I need help because I'm stuck.

I have a Prestashop 8.1.3 with Electron and classic themes. I have created two child themes, one for each. The fact is that with classic I can overwrite without a problem, but with electron's son it doesn't pay any attention to me.

I have also realized that if I do not create the assets/cache folder in the child themes it does not let me activate it; neither the classic nor the electron theme, the backoffice shows me that it is activated, but on the front I get a blank screen. It's the first time something like this has happened to me. I don't know if this has anything to do with the failure of electron's child theme not to overwrite.

I don't think it's a problem with how the child theme is created or with permissions because both child themes are created in the same way and so the classic child shouldn't do anything either.

 

Can anyone shed some light?
