[sergio_varas]

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

Developers options available when store in developer mode. Switch magento in developer mode.

Hi @sergio_varas 

Switch your Magento instance to developer mode by executing below command in your terminal -

• To change the mode - php bin/magento deploy:mode:set developer

• 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!
