Debug tool not working if not in root folder

I am using latest CI 4 version and when I try to use debug tool it doesn't get displayed if CI is in any folder, when I tried on root folder it started working.

So what is issue when I try in subfolder , I do set baseurl properly to subfolder, still it doesn't get displayed.

env set to development
base url = http://domain.com/projects/CI4/public/
writable directory permission "755"

I am getting following error

    GET domain.com/projects/CI4/public/
    [HTTP/1.1 200 OK 997ms]

    GET domain.com/projects/CI4/public/index.php?debugbar

Did you set the base url in the .env file also?

Also set the CI environment to development.

Is your environment variable set with a trailing slash? I had the same problem and this worked for me

Hey guys ! This is a well known issue, which indeed happens when your base_url() is pointing to a subfolder. There are multiple threads in the forum. You should probably do a search :-)
