This looks to me as though the uploads/ directory didn't already
exist somehow.

$ForceMkDir=1 simply tells PmWiki to just go ahead and try to create 
the needed directories without checking the ownerships/permissions of 
the parent first.  It should be a solution for all directories that may
need to be created when running PmWiki.

PmWiki's upload feature *does* give an error when uploading too big a file,
*if* it can determine that this is what happened.  Try uploading a file
larger than 50KB to the Main group on pmichaud.com.  Unfortunately PHP
and the web server don't always provide PmWiki with sufficient (or 
even correct) information when a file upload hasn't succeeded.
