Attachments not working after upgrade (fixed)

[Club3G]

Just went from 3.0.3 to 3.5.3, and I'm getting this error with attachments:

ERROR
The requested URL could not be retrieved

--------------------------------------------------------------------------------

While trying to retrieve the URL: http://www.sevenstring.org/forum/newattachment.php

The following error was encountered:

Zero Sized Reply
Squid did not receive any data for this request.


Any insight appreciated. Thanks!

Bah, figured it out. Directory was 644. Apologies.
