PLESK_ERROR: Template_Exception: httpd: Syntax error on line 353 of /etc/httpd/conf/httpd.conf: Syntax error on line 5 of /etc/httpd/conf.d/security2.conf: Syntax error on line 6 of /etc/httpd/conf/modsecurity.d/zz_rules.conf: Could not open config directory /etc/httpd/conf/modsecurity.d/rules/custom: No such file or directory
Imunify360 extension is installed (Extensions > My Extensions).
Imunify360 extension is not licensed. Directory
/etc/httpd/conf/modsecurity.d/rules/custom is absent, but Plesk tries to uses Imunify360 extension’s custom rules.
Connect to the server via SSH
Create the directory:
# mkdir -p /etc/httpd/conf/modsecurity.d/rules/custom
Purchase Imunify360 license or switch to some of the free ModSecurity rulesets as follows:
