Text file preview failing in Finder (perhaps due to Sublime Text?) I can no longer preview text files (e.g. .txt) in Finder. 

All I get is a preview pane showing a black square and TEXT.



Other files such as .tex files show a normal preview of the contents just fine. I think this changed after I installed Sublime Text, although I could be wrong.

I've tried installing qlstephen but this hasn't helped my problem.

Any suggestions much appreciated!

I had the same problem, without Sublime and I used this instead: https://github.com/sindresorhus/quick-look-plugins
