WP 4.7.1 and Feedzy 3.0.5 Not working – Breaks frontpage

Hi,

Using WP 4.7.1 SE (Swedish) and Feedzy 3.0.5.

It worked perfectly before updating WordPress to latest version (https://sveat.lampeitl.se). But after updating (also feedzy) it breaks the entire page when created using (1) Ruby Composer and even without Ruby composer as seen in (2) it does not show any content.

Not sure why it does not work, settings for the widget is as following: https://drive.google.com/open?id=0B02j83KSqEToQlpvX2pidXJwTXc

Nothing unusual that didn’t work before the update.

1. RUBY COMPOSER PAGES
Correct startpage without Feedzy: https://www.sveat.se
Duplicate where Feedzy is activated & page crashes: https://www.sveat.se/start-page-example/

2. Normally created page
Normal example where feedzy is activated: https://www.sveat.se/om-sveat/

Any ideas of where the issue comes from?

Best regards,
