Not Saving the File

So I was using my kami for a month now and this happened.
Ok, so before this happen, I used Development tool (Ctrl-Shift-I) to edit some file just for fun. And I reloaded it so it deletes the edited file I just edit (and returned to the original ones). And, my Kami now cannot save edited files. I tried to edit the ‘disabled’ to ‘enabled’ but it didn’t work and I have a good internet connection. Please Solve!Picture1

After a day. It works again. So ignore post if you’ve read it.
