Question

I have one codeigniter app which was working fine on localhost. When I uploaded the same on server, it shows blank page & returning no error. I have also used approx. all method mentioned on Stackoverflow or other sites. Kindly guide me.

UPDATES

I found that there is

$this->load->database();

When i remove this, it works, but when I add again, it doesn't work. My site is on shared hosting server

@LalitSharma, I have already enable error_reporting by using ini_set('display_errors', 1); error_reporting(E_ALL ^ E_NOTICE); & my environment set to production — Cool Perfectionist, Mar 24 '15 at 10:58
Then you have to put echo and exit flag in default controller and so on. Hope you will find the problem. — Lalit Sharma, Mar 24 '15 at 11:00
@LalitSharma can you explain how it can be used. My default controller is welcome — Cool Perfectionist, Mar 24 '15 at 11:08
put echo 'here'; exit; in yout index method of the welcome controller, if method is not created then create it — Lalit Sharma, Mar 24 '15 at 11:10
I have checked that there is problem with $this->load->database(); when i remove this from my controller, it works — Cool Perfectionist, Mar 24 '15 at 11:23
it seems CI cannot connect your database and may be your error reporting is off that's why you cannot see any error message. — Shaiful Islam, Mar 24 '15 at 11:44
@ShaifulIslam, I have enabled error reporting. But i can;t understand why my db is not getting connected to CI while my credentials are correct — Cool Perfectionist, Mar 24 '15 at 11:51
Just autoload database make sure you have but your details in you can not load the database library like that has to be done by autoload. — , Mar 24 '15 at 16:06
@guys solved this issue, there is issue with Server PHP version. Now My website is running successfully. Thanks to all participants — Cool Perfectionist, Mar 25 '15 at 05:35

in index.php file located in your base check

define('ENVIRONMENT', 'development');

if it's not then define it same.

Or you can write

error_reporting(E_ALL);

At end of this file, definitely it should work.

I had the same issue Apparently firefox doesn't show any errors (blank page) but chrome shows error 500.

To fix it you need to install php's fileinto extention (extension=php_fileinfo.dll)

Search based on your OS to see how to do it.

I am using XAMPP in windows 7 - I did it as follows :

1-go to xampp/php/php.ini

2-change  
     ;php_fileinfo.dll
to 
      php_fileinfo.dll

3-save the file
4-restart apache from xampp control

First you need to go on root directrory of ci and open index.php file where you get enviornment which by default set to production, so first if you are a developer so change the environment to developer. Then save it and refresh your page. You must show the errors else blank page then if its your database mysql problem then you must firt try this it may help your problem. go to config->database.php and open this file. Where you get

$db['default']['dbdriver'] = 'mysql';

this line you must change this to -

$db['default']['dbdriver'] = 'mysqli';

Hope it will help if not then there must be any other problem. Good luck

Thanks for pointing me in the right direction. After looking at my database.php I notice that I was missing php_sqlsrv_71_ts_x64.dll in my php.ini. – user752746 Mar 28 '19 at 16:22
Great, these small but very huge impact on the framework. – heySushil Mar 29 '19 at 04:40

You must check your php version... and I'm fixing this problem by

$db['default']['dbdriver'] = 'mysqli';
