File upload Problems

[spacecop]

The support from my hoster denied any responsibility for that problem. It says that it is a script problem.

phpinfo shows

open_basedir /users/schule/temp:/users/schule/www /users/schule/temp:/users/schule/www (local value/master value)

is there a solution to by-pass this problem?

I'm a little bit stranded becouse you said its a hosting problem, the hoster says its a script problem...
