Hi -
I know for a fact some servers set another chmod/permission on files uploaded from PHP. I believe this issue was fixed once before by adding a line in the PHP upload code.
Unfortunately, I am not 100% sure where to insert the line of code. I need to ask pain(my partner), as soon as he is available. It would be one of the codes as described on this page:

Pain where are you?
