Those are the COMODO WAF rules you're using when you use their ModSecurity Ruleset. It's noted in the error as well. They are not offered by cPanel and there are commonly issues with them. cPanel offers and provides support for issues with the OWASP Modsecurity Ruleset.This error does not happened before. I am not using COMODO WAF. We are using ModSecurity with COMODO ModSecurity Rules for Apache.
We can rule out an issue with EasyApache by disabling that ruleset then provisioning. If you do not continue to receive an error with them disabled you can safely confirm the issue is with the 3rd party ruleset and you'd need to address that issue with them here: Free ModSecurity Rules from Comodo
