Translations impossible?

Hi there,
I have recently installed neve theme and this plugin.
Major problem for me, it does not work with any translation plugin I have tried so far, and I suspect this plugin is at fault.
What happens is that all looks fine in the backend and in “draft” mode, but once a page is published, only text shows online. So no images, no color, no layout!

Could you please clarify and provide a solution?
Thanks
