Sync turned off notification. I didn't turn it off!

I got a notification that my sync for email was turned off as a pop up. I never touched the setting. Not sure why that is happening.

In the settings master sync is checked turned off. Weird.

Help?

Have you installed any type of app that includes a power optimizer, something that helps to preserve your battery life? I installed the ES Task Mgr app. When I click the Power Optimizer button, my sync gets turned off.
