Hello, I'm experimenting with modules and overrides. I'd love to pack all my modifications to prestashop into one module, but I found that I can override core classes only from the $PRESTASHOP_ROOT/override folder.
The same files, when placed in $PRESTASHOP_ROOT/modules/my_module/override, have no effect at all.
I also couldn't find the class_index.php file indicated in the documentation, I have checked that the www-data user has write permissions in that folder, so what else?
The module was activated in the backoffice, of course, and it displays a nice block in the front. It's only the overrides that do not work.
Thanks in advance!
