Adding the locks solved the error for me, but made the GUI very slow. @Sailor74 i think you posted the incorrect cache.py file, it has no locks. Can you please...

@sergeysi779 Thanks a lot, it fixed it for me as well! One mention though, on my setup the path was different: `/home/pi/oprint/lib/python3.7/site-packages/octoprint_GcodeEditor/static/js`

I just edited the line and restarted Octoprint from the menu. Maybe double check the edit?
