Bitnami & CodeIgniter

I assume you are using the Bitnami "CodeIgniter" installable module?

I suggest installing CodeIgniter into your Bitnami AMP stack manually - I think they use some clever virtual host aliasing that isn't quite what we would expect.

I have done it fine with CI3 install now on bitnami and works fine

But I have also done the same with CI4 and I have set the correct conf files to correct public but the just shows blank page.

Strange.

There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
