Hi, when updating magento 2.3.0 to magento 2.3.1 it happened that the developers option of store-> configuraction-> Advanced-> developers disappeared
I would like to know how I can fix it
now I only see 2 options Admin and System
Switch your Magento instance to developer mode by executing below command in your terminal -
To check the current mode - php bin/magento deploy:mode:show
Once you change the mode, go to the Store -> Configuration -> Advanced and see the magic.
Hope it helps!
