How To Turn On Error Reporting In PrestaShop 1.5

Recently i am working on a prestashop project, i am new to prestashop.So when i am configuring the live site on localhost.After configuration a blank page has been displayed nothing else.I am bit confuse that what is wrong here.I do a google for this and found a lot of post regarding this but none of them is helpful.

They are saying to enable error display through config/config.inc.php file.Through following code.

@ini_set('display_errors', 'off'); to @ini_set('display_errors', 'on');

But when i have opened config.inc.php i have not seen following code(@ini_set(‘display_errors’, ‘off’);) on my file.

So to overcome this i have added this line on line number 29 on config.inc.php, and it will start displaying errors.

@ini_set('display_errors', 'on');
