Your settings could not be saved: Failed saving monetization options

I got this error while saving one of my youtube videos:

Your settings could not be saved: Failed saving monetization options

I tried lot of ways to correct it. But, it wasno successful.

Later signout from my account and retried after 1hr. 

My settings are saved. Its just an error from the youtube site. No need to get panic

Try after sometime, error will be resolved.

Have a good day.
