hi
2 months ago, I have updated the original akismet for php4 plugin (1.0.2).
this release fixes wrong parameters in filterMessage() function since zenphoto 1.4.1.
see the topic : http://www.zenphoto.org/support/topic.php?id=9706#post-57327
I created a ticket with the new php files attached : http://www.zenphoto.org/trac/ticket/1988.
But after verification, the original plugin has not been updated : the php file is alway the 1.0.1 release.
