If its working in your local environment then nothing should be wrong with your PHP code.

Are you getting any JS errors in the browser console?

Well this screenshot has no JS console present.

Right click in the browser =\> `Inspect` and then go into the `Console` tab.

But anyways these are all general webdev questions and not anything specific to CakePHP

your file is called `get_Por_Cidade.ctp` not `get_por_cidade.ctp`  
Watch upper and lowercase letters.

Linux generally uses a case-senstiive file-system (which not all operating systems use per default)  
Therefore it could be, that this worked in another OS which used a case-insensitive filesystem

It worked master, I changed everything to lowercase (getporcidade) within the controller method, within the script and in the view name and it appeared. I even took the get\_por\_city from the view.
