03 Inspections: 06: Configure PHP Mess Detector or PHP Code Sniffer: No PHP in Settings Pane about phpstorm-workshop HOT 4 OPEN

No, your installation is fine =)
In PhpStorm 2021.1, those were moved to the top level, so that it's just Settings | PHP now:

from phpstorm-workshop.

The this text should be changed:
Open the Settings Pane and then Languages and Frameworks | PHP, click the [...] next to the interpreter list, and disable the "Visible only for this project" checkbox for PHPCS and PHPMD interpreter

Then I click ... next to the dropdown menu called CLI Interpreter and there is no "Visible only for this project" checkbox and there is nothing called PHPCS or PHPMD interpreter.

So, where do I find:

• the `"Visible only for this project" checkbox;
• PHPCS
• the PHPMD interpreter
  ???

from phpstorm-workshop.

It all should be there:

from phpstorm-workshop.

In my case, the left of this window is completely Empty... Should this have been installed with the workshop?

from phpstorm-workshop.
