If you have a controller “Blah” and a method “view”, accessing it via the browser like:
results in a “404 not found” error if your PHP installation is PHP v4.4.2. Not verified for any other 4.x versions.
The same code works in PHP 5.2.0-8+etch5, so I believe it is a bug, possibly in system/codeigniter/Base4.php.
I tried to support a bug report, but I need to be registered first, but the registration form for the forums is broken. So here is my bug report.
