1. Log into Plesk
2. Go to Domains > example.com > Hosting Settings and tick the SSI support checkbox > click OK:
   
3. Go to Domains > example.com > Apache & nginx settings > Additional apache directives > add desired directives into the Additional directives for HTTP/Additional directives for HTTPS fields respectively. For example, to parse .shtml files:
   

   CONFIG_TEXT: AddType text/html .shtml
   AddOutputFilter INCLUDES .shtml

   
4. Add to Domains > example.com > Apache & nginx settings > Additional nginx directives:
   

   CONFIG_TEXT: ssi on;

   
   
   

   There is bug PPP-45765. SSI is not enabled automatically for NGINX if proxy mode is disabled. So there is the step to add the directive to Nginx configuration manually.
