Hello,
I’m having the exact same error. I’m using WordPress 4.7.2 and GD hosting so I guess it must be their fault. I never encountered this error on my home page https://hlbenefits.com but mainly on category pages such as https://www.hlbenefits.com/category/health/, https://www.hlbenefits.com/category/weight-loss/ or https://www.hlbenefits.com/category/yoga/
I am currently in the process of contacting them. Will keep you posted
