constant UPLOADS - assumed 'UPLOADS' error

Hi,

I use Ultimate Branding in a multisite WordPress 3.5.1. All is fine on primary website and Network Admin/Frontend, but i have a php error for all other website : `
constant UPLOADS - assumed 'UPLOADS' in /wp-content/plugins/ultimate-branding/ultimate-branding-files/includes/functions.php on line 280 Notice: Use of undefined constant UPLOADS - assumed 'UPLOADS' in /wp-content/plugins/ultimate-branding/ultimate-branding-files/includes/functions.php on line 236 Notice: Use of undefined constant UPLOADS - assumed 'UPLOADS' in /wp-content/plugins/ultimate-branding/ultimate-branding-files/includes/functions.php on line 280 Notice: Use of undefined constant UPLOADS - assumed 'UPLOADS' in /wp-content/plugins/ultimate-branding/ultimate-branding-files/includes/functions.php on line 236`
