I tested IM360 on a second server last week and got some issues.
When IM360 was installed OWASP mod_security rules where installed and activated and that caused a lot of issues for customers since we have Comodo WAF on all servers.
I disabled it and removed OWASP inside WHM and that fixed the issue.
I also see in WHM now:
Home »Security Center »ModSecurity™ Tools »Hits ListDocumentation
That Comodo WAF rules are listing and working fine now!
