Error in upgrading OJS 3.0.2 to OJS 3.1.1

@NateWr I created the error about 6 times in quick succession. In apache2/error.log, tons of these warning messages and nothing else. In apache2/access.log some successful GETs and some 404s from missing favicons, and nothing else. In the postgres error log, nothing. I don’t know where else to look.
