mod_include bug? Options +Includes error... lots of 'em

hey all:

i’m getting lots of entries like this one in all of my site-level apache error logs.

[Wed Sep 16 03:53:50 2009] [warn] [client 80.40.138.30] mod_include: Options +Includes (or IncludesNoExec) wasn't set, INCLUDES filter removed, referer: http://mysite.com/aup.html

i’m pretty sure it has to do with a <Directory> options line in httpd.conf, but am clueless as to which 1 (or more).

Apache 2.2.8 with ver 4.0 CP. Anyone know how to get this resolved? Thanks in advance.
