After the latest update of mod-security for debian squeeze, I am receiving the error message:
Syntax error on line 52 of /etc/apache2/mod-security/modsecurity.conf: Invalid command 'SecRequestBodyLimitAction', perhaps misspelled or defined by a module not included in the server configuration Action 'configtest' failed. The Apache error log may have more information. failed! whenever I try to do /etc/init.d/apache2 reload Before the update it did not show any such error and I did not change anything with the mod-security configuration since. Interestingly, from what I read, SecRequestBodyLimitAction appears only with mod-security 2.6 and squeeze uses version 2.5, so I don't understand why it did not complain before the update.
