CodeIgniter on a live site not loading a controller class

Question

I am trying to set up my site on a production server and basically crash on line 291 in /system/core/CodeIgniter.php:

//instantiate the requested controller // Mark a start point so we can benchmark the controller $BM->mark('controller_execution_time_( '.$class.' / '.$method.' )_start'); $CI = new $class(); 

The class is 'auth' (from the tank_auth library), so it breaks down into '$ CI = new auth ();'

It does not cause an error (why?), It simply displays a blank page. It all works fine.

Has anyone had similar problems?

Answer 1

I had the same problem, I fixed this by installing the php-mysql package:

$ sudo yum install php-mysql

Answer 2

Have you noticed if error reporting is enabled? If not, try adding

 ini_set('display_errors',1); error_reporting(E_ALL); 

to the beginning of index.php.

Answer 3

Check this topic for a similar problem: CodeIgniter project loads a blank web page

In addition, if you do not have mysql and / or a database installed for your site, TankAuth needs a database. Be sure to follow all installation instructions and create the tables that the module needs (you will see a .sql dump in the downloaded folder),

Answer 4

see include_path in php on your production server and / or make another interface with the development environment to see the error

Answer 5

I had the same problem, in my case I needed to install php-pgsql lib (because I use postgresql) on my server. After that, the problem was resolved.

Answer 6

My solution was the same as the others, to establish mysql compatibility with php. In my case, the platform is ubuntu on Amazon AWS (using mysql on RDS, not local):

$sudo apt-get install php5-mysql

$sudo apt-get install mysql-client

$sudo service apache2 restart

And that’s it, Hello!

Answer 7

Add the same problem to cpanel by moving your CI project from php 5.3 to 5.4

Blank page error or 500 internal server errors

This will fix the problem:

Enable the mysqli extension in PHP (v5) via EasyApache using the comprehensive options list (Cpanel).
