Having used Sugar CRM for a few months I now need to upgrade from 3.5.1a to 4.0.1 and I've hit a problem trying to use the upgrade wizard. I upload the file then get the following messages:

-Warning: Your PHP configuration must be changed to allow files of at least 6MB to be uploaded. Please modify the upload_max_filesize value in your php.ini located at:

-Please specify a file and try again!

The first message is not an issue IMO. 'upload_max_filesize' is currently set to 10mb and the upload file is only 3mb anyway.

Can anyone shed any light on what I need to do to get this working?

A little detail:
OS is Suse Linux
Tried to upload using both Firefox and IE (both same result)
File I'm trying to upload is called: "SugarSuite-Upgrade-3.5.1_to_4.0.1.zip"

Anything else you need to know, please ask.

Big thanks to anyone who can help
