I am receiving an error message for one of the sites I work with from Mod_Security that I am not exactly sure what to do with.  Can someone assist with a rule to bypass this?

mod_security: Filtering against POST payload requested but payload is not available [hostname "www.xyz.com"] [uri "/cgi-bin/order/login.pl"] [unique_id "R1BOWUEnz2MAAH4xvLQ"]
