The discussion form is embedded to the homepage and shows just fine. The issue is when you go to click on a link, it takes you to a blank page with the error message "Not Found" 

This is not my personal site, I am assisting the owner with some updates to it. I am not familiar with WpForo because it was set up by someone else prior. I'm reaching out for assistance because I don't want to go in there and potentially mix something up. Thanks!
