WPP Stopped working – no data

Hi guys, the plugin was working great, i have multiple shortcodes displaying the posts i require. I’ve gone on the dev site today and the posts were no longer showing. They were replaced by a loading line… I’ve cleared the cache, disabled stack cache, reinstalled the plugin and now i get no data message. I’ve clicked through numerous posts but nothing shows in the statistics in the back end and nothing pulls through on to the site… I’m at a loss any help would be much appreciated! Thanks!
