Error shows "Failed to get text for stylesheet (#): No style sheet with given id found", what does this mean?
I had the same problem. It looks like a bug in Chrome's live-edit CSS/JS. Notice how the number changes on each request.
I fixed it by closing all the files that I had edited in the dev tools 'source' tab and then refreshed the page.
The error went away after I closed all the files in the 'source' tab.
I tried to reproduce it after closing the files, but I can't seem to recreate it, yet.
Here is a picture showing where to find the 'source' tab:
