Large file upload

Hi,

I'm trying to upload large files via my homepage. I'm using a form:
    print "<form enctype=\"multipart/form-data\" action=\"approve_element.php\"
method=\"POST\">";

And with files up to approx 500kb it works. But with larger files, the
browser can't find the page, and if I refresh the page, I get some query
errors. In the php.ini the post_max_size is set to 8M.

Kelvin :-)
