installed cwaf rules, now?

i installed first modsec with owasp rules, then i installed cwaf (comodo) rules following this guide
https://panel.bullten.net/knowledgebase/48/Install-ModSecurity-and-Comodo-WAF-in-CWP.html

but i can't access the log it says at the end, it doesn't exist
looking at cwp (not terminal), mod security conf, i didn't find the include, so i wrote it by hand in configuratioon file

now...
can owasp be not compatible with cwaf? how can i disable owasp and leave cwaf?
thanks
