This is because your server has PHP safe_mode activated (which has
nothing to do with Pmwiki). For more information about safe_mode read
this page, http://se.php.net/features.safe-mode. From what I can see
your uid as a user is 68717 and your webserver is running with uid
109. Safe_mode prohibits a script to change a file owned by another
user, i.e. your script (you own that file) can't change a file
uploaded by the web server, since that file is owned by the web
