I have a local install of ghost where I edit my theme every now and then.
I have been doing this for a couple of years now, with no problem at all.
Now when I try and download a theme from production server and import into my local development area, I get a “Something went wrong :(” message.
Nothing has changed locally.
Both servers are running same version of Ghost.
I have even tried importing versions that I 100% know have worked in the past. Absolutely nothing works.
I have tested the themes and no major warnings appear using the theme checker tool.
