Hi,
I installed PrestaShop successfully, used the installation assistant and enabled the "demo" mode to see how it looks.
Great, but from the back-office I cannot do any action, like updating settings, adding a theme...
For whatever reason it says in french "This feature has been disabled"... But what... no endpoint at all is usable 
. Is it a normal behavior? Due to new versions? I didn't find tips on forums.
I thought about the demo mode restricting access, but I don't find in the UI where to disable this.
Thank you,
EDIT:
It seems indeed coming from me having enabled the demo mode... https://github.com/PrestaShop/PrestaShop/blob/c719b308029ec00a7b5a182c5a8323867c7b7e74/controllers/admin/AdminTabsController.php#L282-L286 I need to find where this parameter has been saved in my container/database...
EDIT2:
Ok I succeeded after seeing when using Docker with `PS_DEMO_MODE: 1` it will hardcode in a file the setting: https://github.com/PrestaShop/PrestaShop/blob/c719b308029ec00a7b5a182c5a8323867c7b7e74/.docker/docker_run_git.sh#L150
The solution for me was to do the reserve operation:
`docker exec -it xxxxxxx sed -i -e "s/define('_PS_MODE_DEMO_', true);/define('_PS_MODE_DEMO_',\ false);/g" /var/www/html/config/defines.inc.php`
Then restart, and it's fixed!
