Error Saving Settings

When trying to save my settings I get the following error message:

app.js: 18313
Uncaught TypeError: undefined is not a function

I get this error when I try to save on any of the Settings pages. Any idea what this could be from?

Thanks for any help

Which version of Sonnar?
Which OS and browser are you accessing Sonarr from?

I was having the exact same problem, Running v2.0.0.2663, from chrome ~39.something… (dont remember)

I then went to firefox, v34, tried the same save command, and it worked great. Then I updated firefox to v35, and then chrome to latest v40, and tried saving and changing things, and everything seems to be working fine.
