Doing an automatic upgrade from 2.7.x to 2.8.5 gave the below error message. Accessing the site again redirects to the
page, still giving the option of upgrading from 2.7.x to 2.8.5.
Any suggestions on how to troubleshoot or fix this (I haven't retried upgrading a second time in case that would make matters worse.)
