No error on non-writable logs directory?

Sounds like this is because a critical php error occurs, but you have php ini display_errors set to 'off' so you see a blank page.

In your index.php file put

ini_set('display_errors', 'On');
error_reporting(E_ALL);

Refresh and see if you get a php error - I suspect you are getting an error for a different reason than you think because. I could be wrong.
