    The most recent update just put a stranglehold on my Easy Digital Downloads, throwing the following error whenever someone tries to download a fie:

    PHP Fatal error: Uncaught Error: Call to undefined method GuzzleHttp\Promise\Coroutine::of()

    Disabling Pixel Caffeine resolves the issue.

    Please advise.
