After upgrade issues

Hi everybody,
Thought to start here before anything. So I just upgraded our theme (Newspaper) from an old V.7 to the latest V.10.3.4 The upgrade went ok without any issues (plugins also updated ok) but after it was done (and maintenance mode off) a few issues happened such as missing many pictures (they are shown if clicked on the white area where they should be displayed) and also many of the pages now load with sort of a mobile view (on a desktop PC)
So far this is what I’ve found (just been checking for a few minutes but this issues make our site pretty much impossible to browse.

Any ideas are greatly welcomed :slight_smile:

I don’t think we could offer anything except paid support as the reason behind of it may be something else that we cannot even guess
