The following ModSecurity error message appears in the Application log of the Event Viewer:

The description for Event ID 1 from source ModSecurity cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

OWASP (free) is being used under Tools & Settings > Web Application Firewall (ModSecurity)
Experimental rule-set (owasp_crsexperimental_rules) is enabled in the ModSecurity configuration file C:Program FilesModSecurity IISmodsecurity_iis.conf.

Going to Tools & Settings > Web Application Firewall (ModSecurity), shows that ModSecurity 2.8 or higher is installed.

The directive SecReadStateLimit has been deprecated starting with ModSecurity version 2.8.0.

This error message can be safely ignored as there is no impact on the ModSecurity operability.
