Visitors coming from Google search links get blank page, Error 500

Hello, I am finding that all links from google search end up leading to blank pages, however refreshing the page fixes the issue.

This is one such link

https://www.google.co.uk/url?sa=t&rct=j&q=&esrc=s&source=web&cd=11&ved=0CFQQFjAKahUKEwi-kOzVyvHIAhXGvRoKHcZaBtE&url=https%3A%2F%2Flondonrealacademy.com%2Fepisodes%2Foren-klaff-how-to-pitch-anything%2F&usg=AFQjCNES1nwwIbdTNCsLRNiR5I8-17DLbQ&sig2=hHMt4fHntOSHVpRCvDYNXA
