I wasn't sure where else to ask about this one, but thought if any progress is made it is useful as part of setting up Drupal.
I've got a Drupal 7 installation working perfectly with clean urls locally. But as soon as I upload to the server, clean URLs causes all POST requests to be empty.
That is, $_POST is completely empty as well as file_get_contents('php://input') being empty.
If I then turn off clean urls, it works fine again. All GET requests and other pages work fine with Clean URLs though.
PHP version is 5.3.3. post max size is 8M.
