I don't want keep getting email from Facebook's updates. So I go to notification setting in my Facebook account, but this is what I get
So I get all the check boxes and the save change button disabled
What should I do?
There is the email frequency checkbox to check or uncheck. It's under Down-arrow in the upper-right corner → Account Settings → Notifications. You can check it if you want emails sent to you about being tagged in a photo, payment confirmation, security or privacy information.
Uncheck the Email Frequency checkbox then try again, the checboxes will be enabled.
