Hi friendly Umbraco folks,
I have a website (originally v7) that I’ve upgraded recently from 13.4.1 to 13.7.2 and preview has stopped working - just a blank page, and the device title is {{previewDevice.title}}.
The console shows a 404 on umbraco/lib/LazyLoad.min.js. There’s no /lib folder under /umbraco on disk - even on a clean install where preview works - so can anyone tell me where these js files are being accessed from, and what might be stopping them being found?
Thanks!
Chris
