I am in the process of trying, but not all the files it says to remove are listed… Ugh!
The issue is, we cannot get access to the dashboard to do anything.
I am having the same issue. After updating to WordPress 4.7. I found on Forum READ THIS FIRST WordPress 4.7 Master List that: W3 Total cache – Version 0.9.5.1 is incompatible with WordPress 4.7and it must be deleted entirely. I did this on 2 other sites and update worked fine. Unfortunately I did not remove it from 1 site and am going to try to restore a back-up to see if I can remove it. If anyone has any ideas on how to remove W3 post update, that would be very helpful.
