Are AJAX requests in PHP 8 compatible with CodeIgniter 3?

Are AJAX requests in PHP 8 compatible with CodeIgniter 3?

I successfully installed an application using CodeIgniter 3, which has been working flawlessly on PHP 7.4 for quite some time. However, when I attempted to install the same application on another machine running PHP 8.1.2, the AJAX requests stopped functioning properly.

I think you need to check the logs or the server response with an error

What means stopped working properly. ChatGPT: Act as an tester... haha..

Ok, just to make sure it is ajax request, have you send X-Request-With header? What does error/debug logs saying? Web server access response codes? Whatever just follow the white rabbit request chain!

Use your Web Browsers Developer Tools Hit F-12 key on most Web Browsers.

Click on the network tab.

What did you Try? What did you Get? What did you Expect?
