Hi. I keep getting this error when I try your plugin:

Class 'GuzzleHttp\Client' not found.

It has also failed on the OctoMail plugin so I'm not sure what's causing it. I've tried adding Guzzle using this command, composer require "guzzlehttp/guzzle" "~4.0", but it has not solved the problem.

The weirder thing is that it used to work before on a different machine. After I moved the site over using Dropbox it started acting up.

Well nevermind. It looks like reinstalling the site worked. Thats just weird. :/

Please don't spam the forum multiple times with the same post.

Ok sorry. I did it in multiple sections because it could have been either a plugin problem or a core problem. Thanks for letting me know
