Well its another strict standard error, you may just turn it off it annoys you. Note strict standard errors by default aint enabled in PHP 5.3, which is why the script wasnt tested against it when it was released.

Oh another. Download the two other attachments and upload them to /classes folder, it should fix every strict standard error though. Alternative, you may disable error reporting for strict standard, as it doesnt really make your site stop functioning.
