Fatal Error Zend_Uri_Exception

I really, really want to use this plugin, but I am getting an error when saving a page to Draft or on page Preview.

I have tried using the channel in the instructions

GoDaddy Managed WordPress version 4.9.8 – PHP version 5.6 (upgrading soon)

Getting a fatal error:
