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
