Portfolio Pages Not Working

I have this website where we are using the portfolio to list out team members and speakers. The portfolio images are displaying but when you go to click on the image or the text to take you to the detail page they are all broken.

The WordPress version is current 4.7.4 and all of the plugins are updated.

Here’s a list of the plugins:

– CF Post Formats
– Contact Form 7
– FlexSlider
– Post Types Order
– Recent Tweets Widget
– ShareThis
– Twitter
– UpdraftPlus

What should I look into to fix this? Has anyone else reported issues? I looked in the list of topics but I didn’t see anything.
