I am running php 5 with apache on windows 2003. I have changed the the upload_max_filesize to 50mb. I have saved the file and restarted apache. When I try a file upload in Drupalit says the maximum file size is set at 8mb allowed by php (this is reported where you set the limit for drupal). Do you know where I would change this option to make it more. I believe it to be a server setting rather than an application one.
Check the post_max_size in php.ini:
post_max_size = 8M (max size that a script can POST back)
