"We The People" Wordpress Plug-In isn't finding my Petitions from WhiteHouse.gov

[Distance-Everheart]

 I've created several petitions on WhiteHouse.gov and installed the We The People Plug-In.  I've inserted my API number, however when I click the "Insert We The People Petition" button on the back end of Wordpress, the "Find a Petition" (to find the Petition ID) is not pulling up any of my petitions.

Here's a link to one of my Petitions I'd like to embed into the page. Please help:
