After upgrading to civiCRM 5.4.0, I cannot access latest version of civiDiscount via the civiCRM menu.
I see the option under Administer and Contributions, but when I click civiDiscount, I am returned to the civi Dashboard, instead of seeing the civiCRM interface.
There's no error logged by civiCRM.
I'm also running Joomla 3.8.11
