*SIGH*, nope.
I replaced attachment.php, newreply.php and newthread.php with a clean one.
No such luck.
Xenon, can you visit my forum and attach something to a post (you'll have to register first :P, but if you PM me I'll set you up an account).
At least then if I know it works for you, it's just this computer.
Dave.
PS: Wait a sec.
I'm hosted on tripod lycos (as a last resort), and ini_get has been disabled.
I looked through newreply.php and found this:
PHP Code:
} else if (ini_get('file_uploads')) {
$enctype = 'enctype="multipart/form-data"';
} else {
ini_get was disabled, so could this be the reason?
