First time online Model partly works - SOLVED

Hi there,

It's my first time uploading CI-4 project online after my local works. I have faced an interesting situation. Everything looks fine actually. My pages work, I can list all records from my database but I cannot login/register or save any new data like I easily do on my local. It looks like my Models partly work and I cannot use my system.


Anything that comes to your mind related to this issue?

Some info:

Shared Hosting,
Manuel setup
PHP Version 7.3.25,
zlib.output_compression Off,

Thanks in advance
