Configure Varnish Cache for Wordpress

I have a Litespeed Webserver with cpanel, and PHP 7. My website is wordpress 4.7. Problem: I installed xvarnish cache, and I have it partially working, however, when anybody clicks a link on the pages, it serves a 500 error. If the page is served directly it seems to work fine. I cannot figure out how to get around this. I need varnish configured properly so that I do not get 500 errors when users use my wordpress website. I need this done ASAP, so do not bid if you are not available to start now. Lowest bidder will win.
