Error on editing folder scan interval


I often come accross this error when I try to change the scan interval of a folder after I click Save. I think it append when syncthing is scanning a folder when I save the change. And of course the changes are not saved.

I have big folders (compared to the power of the server) so it’s scanning all the time when the interval is 60, which make it near impossible to change from the WebUI.

Can you check the javascript console for errors and responses to requests?

It could also be this:

I cannot reproduce it, maybe you’re correct. I might had another instance running somewhere in the background.

Will send the log if it happens again.
