Database Connection Problem

Set the environment to development mode
for CI4 this is done using:
(just put this line at the beginning of the /public/.htaccess)

PHP Code:

# Setup environment
SetEnv CI_ENVIRONMENT development 


next, reload the page, and attach the resulting images to your next post. or just send us the code you are working on, it will give us more information to help you.
just if you can then send logs from the directory "writable/logs"

I would change this world, but God doesn't give me the source.
