I'm running into an issue where the plugin - when activated - makes the deploy from staging button in the WP Engine back end not work on the site. You have to disable the plugin, deploy, then re enable the plugin. The site is under active development so that's a bit of an issue. I've tested it all and this is the only plugin that is causing the issue.
To access the site you're going to need a username and password to bypass the HTTP block on it.
I've also identified that I'm getting the following error on the screen with the plugin activated:
caught TypeError: Cannot read property 'length' of undefined
