problem with template

sorry for my english
good morning, i have a problem when i load a new document in front-end. if i use the default form, no problem, if i try to use the simple form it doesn't load any document. are there any specific php prerequisites, or other requirements.

Hi Livio,
Could you please submit ticket on category: Edocman and provide your site credentials. I will check the problem with Ajax Upload form for you.
Thanks
Dam
