Yeah, I am trying to find php.ini :-).But thanks for the reply!
go to administration on server php and find
php_admin_value[post_max_size] = 100M
php_admin_value[upload_max_filesize] = 100M
I did that earlier, but nothing happened. It is probably in the php.ini file then..
It's weird, if you didn't change anything in the code it should work without a problem
