It works, but I had to move the script that execute the upload. I put the script in the main folder (public_html) and it is okay. It looks like the php.ini that I created does not modify the scritpt present in folders inside public_html (public_html/private). Is that correctly?
If you want the php.ini settings to propagate down into your subfolders you need to add the following into the .htaccess file in your public_html folder;
suPHP_ConfigPath /home/username/public_html
(replace username with your actual account username)
