带有codeigniter的死亡白屏

Question

I have move a codeigniter script from a development server to production server (

same server, just different domains, so no PHP/database/apache config/ or related issues

)

I have been able to get log in just one place /application/logs folder I have tried everything else for logs ( enabled php logs etc etc.) nothing seems to show me what is the issue, what's causing white screen)

If anyone has any idea, please let me know so far I have

Added development server in index.php Googled, and tried everything else for some error to show up, nothing worked till now.

I am kinda out of ideas for now.

Got some entries in server now, but they appear to be more of hack attempts than actual errors.

Answer 1

I have face this issue because of the DB Driver is not responding.

go to application/config/database.php

---

If codeigniter 3.0- ( less than 3.0)

$db['default']['dbdriver'] = ''; # Change to mysqli

If codeigniter 3.0+ ( greater than 3.0)

'dbdriver' => '', #  Change to mysqli

Answer 2

Thought I'd reply to this as it came up top in the searches when I was looking for an answer...

I found the answer by looking in the console on Chrome when I got a white screen. There was just this error:

Failed to load resource: net::ERR_CONTENT_DECODING_FAILED

The solution was to go to the config file ( /application/config/config.php ) and find $config['compress_output'] . In my case this was set to TRUE - change to FALSE and you might be good to go...
