Hi,

Doing an automatic upgrade from 2.7.x to 2.8.5 gave the below error message. Accessing the site again redirects to the

.../upgrade.php

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.)

Thanks!
