      Using docker and docker compose
      1. git clone https://github.com/mainflux/ui.git
      2. cd ui
      3. docker-compose -f docker/docker-compose.yml up
      4. http://localhost //UI is up // logs are running in the background
      5. Register/Sign In with emailId and Password.
      6. Go to Things --> Devices --> Click Under Actions "+" Button.
      7. New Row is added here we can give only Name rest other fields ie [Type , ID] are NOT editable
      8. Give some name say "Device1" and click save ie "Tick" button
      9. Now try to delete the Device1 , UI will prompt you for deletion press Submit

@delvinggeeks Looks like it's not an UI bug. It was fixed here: https://github.com/mainflux/mainflux/pull/1220
Please, pull latest core services and try again. If it still don't work open an issue in mainflux/mainflux repo.

Hi @manuio . I have made a diff compare between ui docker-compose file and mainflux docker-compose file logically i dont see any major change. The above problem arises only with ui component but with mainflux either using cli or curl we can delete thing without any problem
