Embarrassment

This plugin is an embarrassment for Zapier. It hasn’t been tested with the last 3 major releases of WordPress, it gives a ‘no valid header’ error when installing and despite that it hasn’t received an update in the last 6 months.
When you feel adventurous and work to get the plugin running after all you find out that it doesn’t even retrieve the custom user roles from your WordPress install and creating a new user with the right role simply doesn’t work.
I’ve worked with Zapier a lot and this is really disappointing that they let this clunky piece of code out in the wild.

Don’t loose your time on it.
