Imunify360 extension was removed and there are leftovers in the ModSecurity additional configuration.
Connect to the server via SSH.
Back up the Custom Directives configuration file from ModSecurity:
# cp -a /etc/httpd/conf/plesk.conf.d/modsecurity.conf /root/modsecurity.conf.backup
Empty the Custom Directives configuration file from ModSecurity:
# echo “” > /etc/httpd/conf/plesk.conf.d/modsecurity.conf
Go to Tools & Settings > Web Application Firewall (ModSecurity) and enable it with the necessary ModSecurity ruleset
Note: In case it’s necessary to use Imunify360 extension, uninstall and reinstall the extension back on the system
