Welcome to the forums!
If you are trying to use a .htaccess file make sure you have a ? in your rule.
Code:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
In your application/config/config.php bump your $config['log_threshold'] to 4, and reload the page. Then check in /system/logs for a file created on todays date. Also check in the index.php in your root for your error_reporting level
Code:
error_reporting(E_ALL); //This should display errors
Typically the blank screen is caused by a php error with error_reporting() turned off.
