Ah see that's the weird thing. I can't get to that point. So, let's say I have the form action directing to page X. We never get to page X: the page literally re-loads, blanking the form field in the process, and any instructions are ignored, or never found. If I then hit submit again, with the file upload form field blank, it goes to the target page and does whatever I want-- in this case giving me error 4 since there's nothing there anymore. You see what I mean? But if I go to load a JPEG, for example, it goes write to the specified page and does whatever. Hence my confusion.... Again, the max file upload size should be no trouble. I'm wondering if there's some other php.ini thing I'm neglecting, or possibly some Apache thing...?
Thanks for writing.
