Codeigniter, blank page, no errors [closed]

Answer 1

if you changed the file names, you also need to change the class names:

A file named my_class.php needs to have: class My_class extends CI_Controller {

so, if you took a working controller, copied it, and renamed the file. Then you also need to rename the class.

Answer 2

You can easly check what's happening in the enteire envoirment by enalbing CI logs,

go to config/config.php and edit this:

/*
|--------------------------------------------------------------------------
| Error Logging Threshold
|--------------------------------------------------------------------------
|
| If you have enabled error logging, you can set an error threshold to
| determine what gets logged. Threshold options are:
| You can enable error logging by setting a threshold over zero. The
| threshold determines what gets logged. Threshold options are:
|
|   0 = Disables logging, Error logging TURNED OFF
|   1 = Error Messages (including PHP errors)
|   2 = Debug Messages
|   3 = Informational Messages
|   4 = All Messages
|
| For a live site you'll usually only enable Errors (1) to be logged otherwise
| your log files will fill up very fast.
|
*/


  $config['log_threshold'] = 0; //put this to 4

then if you have not yet a /logs folder inside your /application folder, create that and add 775 chmod to that (logs folder only).

UPDATE: You must also chown apache:apache logs in order for apache to be able to write within that folder.

run your application by the browser and check inside your /logs folder the log.php file, it will contain all the application errors.

Answer 3

To see the errors instead of a white page, you need to change two options in the php.ini file:

• error_reporting to E_ALL
• display_error to On
