Upload has issue with some files "You did not select a file to upload"

[quote author="Diggory Laycock" date="1224871266"]After a bit of reading the PHP docs I noticed this:

if POST size exceeds server limit then $_POST and $_FILES arrays become empty. You can track this using $_SERVER['CONTENT_LENGTH'].
For example:

Settting higher post_max_size (and, of course, upload_max_filesize) value helps me in the same problem.

Diggory Laycock, thanks.
