Sometimes when we developing our Codeigniter application, suddenly it gave us White of Screen or blank page error. To solve this problem, we need to configure our PHP.ini to show error. So, if you using Ubuntu, go to /etc/php5/apache2/php.ini and edit :
1 2 | error_reporting = E_ALL | E_STRICT display_errors = On |
If you still facing blank screen then you should check error.log in apache2 by “tail -f /var/log/apache2/error.log”.
Now you should know what makes Codeigniter have a blank screen page.
