Error message 'you are in preview mode…"

  • I keep getting an error message every now and again when I try to select articles from the Guardian News Feed in posts. At the top of the page it says: “You are in preview mode. This plugin requires an access key in order to publish articles from the Guardian…” I already have a valid API. At the bottom of the screen it says this:

    Warning: Invalid argument supplied for foreach() in /home/content/92/3511392/html/wp-content/plugins/the-guardian-news-feed/gu-open-platform-article-importer.php on line 321

    Does anyone have any ideas on how to fix this?

    Thanks!
