Codeigniter 4 Modules not working perperly : I have been trying to setup codeigniter 4 modules but it seems something is not working properly 
it takes me to 404 or not found. 

i have gone through this doc : https://codeigniter4.github.io/CodeIgniter4/general/modules.html?highlight=modules 

I have simply installed Ci4 and follow this doc did not tweaked anything else as we do in previous ci 3 hmvc practice. 

is there anything else beside autoload ? 
I'm basic php dev. please guide. 

thanks.
