Hey dudes is it me or the previews really do not work? I am getting the error page. I tried the top 4 templates on the templates list.
They’re now working again.
It was my fault. (The full screen previews run off a different HTML template to the rest of the site, and I neglected to update it when I was making some changes to the underlying code.)
I’m adding some automatic tests to make sure it won’t happen again.
