Blank Screen with CodeIgniter

Things to check:

• Inside config.php, make sure your $config['base_url'] is set properly
• Were you able to copy your .htaccess as well?
• Do you have the same PHP versions in both machines? If your answer is yes, i'll ask you again: Are you sure?
• What is the value of your $db['default']['hostname']?
• Do you have the same database setup in your local and production server? There could be differences with the hostname, username, password and database name

Other things you can do:

• Set $db['default']['db_debug'] to TRUE
• Deploy a fresh CodeIgniter installation in your production server and check if you can see something
• If you still see a blank page, deploy a single PHP file with text in it and tell us what you see
