I'm running magento 2.3.0 on php 7.1
I have two users each with a different user role/permissions created
Users | User Role | Role Resources (resource access)
----------|--------------|-------------------------------
Admin |Administrator | All
dev |Dev | Custom (everything except permissions)
Issue 1
When a module was installed using the dev user and on logging in with the admin user the admin panel is completely messed up. Clearing cache did not help.
Issue 2
When logged in as the dev user the theme settings don't show up as they do when logged in as the admin user. As the below images show
View from dev user login
(missing theme "wokiee" on left menu panel and within stores >> configuration)
View from admin user login
(shows theme "wokiee" on left menu panel and stores >> configuration)
