Error: New configuration files for the Apache web server were not created due to the errors in configuration templates: apache2: Syntax error on line 222 of /etc/apache2/apache2.conf: Syntax error on line 3 of /etc/apache2/conf-enabled/00_mod_security.conf: Cannot load /etc/httpd/modules/mod_security2.so into server: /etc/httpd/modules/mod_security2.so: cannot open shared object file: No such file or directory.

Please remove and then reinstall ModSecurity through the Plesk installer.

I tried that through the web interface and terminal, it didn't create the file mod_security2.so
The only way to get apache started was to comment out loadmodule in the 00_mod_security.conf
Modsecurity 2.9 fails to start but if I switch to Modsecurity 3.0 it will start.

Did you click both on the left and the second one in the Plesk error message?

The configuration files should be regenerated.

login via SSH and run apt-get update next apt-get upgrade are there any errors?

maybe you need to run:

apt --fix-broken install

never delete plesk packages by doing this.
