When verifying the config I am receiving the following warning:

[The following errors were not caught before. Please correct the script in order to avoid future disruption. "unexpected end of arguments;expected argument spec:HEADER_VALUE"366 65][ACCESS::respond 403 -version "1.1" noserver "Connection" "Close"]
