Hi Laurent,
i'm working on a new plugin an this needs a backend.
Everytime when activate, deactivate or uninstall the plugin the management does show me an unknown status.
The reason is that the status is
Quote'disabled'
'todelete'
'enabled'
This will only with sinlge quotes when the plugin has a backend. When i remove the backend folder the status works fine.
You can test it with this simple plugin...
