Upon activation, bricks website (error 500)

Hi there, just a heads up here, I’m trying to install the latest version of this plugion on 4.7.2, and upon activation, it produces a site-wide error 500. I’ve used the plugin on many sites with the same set up, but not on 4.7.2, and never had this issue. Not sure if this is a bug or?

Great plugin when it works though!

Thanks
