Uncaught Error: Call to undefined function getallheaders()

[chromahoen]

Glad that you wrote this. Thank you... After installing in 5.3.2, I get an error just loading the site. Even loading while not on the page that holds the form. Any ideas?

WordPress version 5.3.2
Current theme: UnderStrap Child (version 0.5.0)
Current plugin: Referrer Field for Gravity Forms (version 1.0.1)
PHP version 7.1.17

This plugin doesn't work - it's just something we were testing. We have a new version in development but no eta on the release at this time.
