After El Capitan update, I can't update iPhoto. Here is the message: This update is not available for the Apple ID either because it was bought by a different user or the item was refunded or cancelled. Neither of these are true. I'm stumped!

Welcome to Apple Support Communities
Did you purchase iPhoto from the Mac App Store (or did it come with your Mac)? If your Mac was bought after the OS X Lion release (July 2011), maybe iPhoto is hidden in your purchases list. To see if you can unhide it, follow these steps -> Hide and unhide purchases in the Mac App Store - Apple Support Then, try updating it again. If it does not work, contact with the Mac App Store support team -> http://www.apple.com/support/mac/app-store/contact.
Note that OS X El Capitan includes the Photos app, that replaces iPhoto. You can find it in the Applications folder, and if you do not like it, your Mac will keep a copy of your iPhoto library in order to use it again.
