I'm unable to install, update or download apps

I get the error message: Unable to install Whatsapp. The app could not be installed.

I checked everything in my app store, payment details etc. and all seemed fine. I even restored the phone and put the back up that I did before restoring. It happened after upgrading to 11.0.1

Can anybody help?

iPhone 6, iOS 11.0.1
