Hi @G17creative - I’m guessing you’re running a version of PHP lower than 7.1.0? Is that correct?

[G17creative]

Hi @joshangell, thanks for getting back. That's correct, it's just 7.0.33

[joshangell]

Aha OK then - you will need to be on at least PHP 7.1.0, see here for reasons why: https://www.php.net/manual/en/functions.returning-values.php#functions.returning-values.type-declaration

I will leave this open for now until I force that requirement in the README and with composer.
