Blank Screen with code igniter... help?!!!

Question

Hi, I've just moved a site across to a production server, and a once working CI installation, now returns a blank screen.

I believe it is due to whitespace, but how are you supposed to find something like that?!!!

Hope someone can help. Thanks in advance. Tom

Answer 1

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

I experienced the same issue and I solved it by setting my log-folder to writable. It seems, that if you turn on logging, and your log-folder on your server is not writable, CodeIgniter just shows you an empty page.
